Reading multiple spreadsheets in google app script

I'm trying to get all text from a specific cell of all spreadsheets in a folder. My current issue is I can only read them in as a file type which doesn't allow me to access the getRange() function.
Here's my code so far.
function createLog() {
var folder = DriveApp.getFolderById("id#");//not placing actual id for privacy
var contents = folder.getFiles();
var data; //array for relevant text
var file;
var d = new Date();
var log = SpreadsheetApp.create("Events log "+d.getMonth()+"/"+d.getDay());
while(contents.hasNext()) {
file = contents.next();
file.getRange("A6");//error is here because it is a file type not a spreadsheet
}
for(var i =0; i<contents.length;i++){
log.getRange(0,i).setValue(data[i]);
}
}

Once you have the list of files you need to open them with SpreadsheetApp. Then you can work on Spreadsheet using the Sheet and Range functions.
var spreadsheet = SpreadsheetApp.openById(file.getId());
var sheet = spreadsheet.getSheetByName('your sheet name');
var value = sheet.getRange("A6");
See:
https://developers.google.com/apps-script/reference/spreadsheet/spreadsheet-app
https://developers.google.com/apps-script/reference/drive/file#getId()

Cameron's answer is correct but I suggest to open spreadsheets by ID instead of names because in Google Drive many files can have the same name...
Below is a simplified demo code to test the idea and a few comments to highlight what needs to be adjusted
function createLog() {
var folder = DriveApp.getFolderById("0B3###############ZMDQ");//not placing actual id for privacy
var contents = folder.getFilesByType(MimeType.GOOGLE_SHEETS);
var data; //array for relevant text
var fileID,file,sheet;
var data = [];
var d = new Date();
var log = SpreadsheetApp.create("Events log "+d.getMonth()+"/"+d.getDay());
while(contents.hasNext()) {
file = contents.next();
Logger.log('Sheet Name = '+file.getName());
fileID = file.getId();
sheet = SpreadsheetApp.openById(fileID).getSheets()[0];// this will get the first sheet in the spreadsheet, adapt to your needs
data.push([sheet.getRange("A6").getValue()]);// add a condition before this line to get only the data you want
}
log.getActiveSheet().getRange(1,1,data.length, data[0].length).setValues(data);
}

Cannot call method "getEditResponseUrl" of undefined on Google Apps Script bound to Sheet when opening form using form ID

I have this function which works but it gets all responses.
function setEditUrl(ss, createDateColumn)
{
var formURL = 'https://docs.google.com/forms/d/101bMiRw9TQaGbdDc4U_tLAD0QzicqejM9qXOEwJPQKU/viewform';
var urlColumn = createDateColumn-2;
var data = ss.getDataRange().getValues();
var form = FormApp.openByUrl(formURL);
for(var i = 2; i < data.length; i++)
{
if(data[i][0] != '' && data[i][urlColumn-1] == '')
{
var timestamp = data[i][0];
var formSubmitted = form.getResponses(timestamp);
if(formSubmitted.length < 1) continue;
var editResponseUrl = formSubmitted[0].getEditResponseUrl();
ss.getRange(i+1, urlColumn).setValue(editResponseUrl);
}//end of if
}//end of for
return;
}// This is the end of the setEditUrl function
As the spreadsheet gets larger I am concerned with performance lag so I want to streamline it and replace the function with one like the one below which just gets the editURL for the last response and only if the sheet cell is empty
function setGoogleFormURL(ss, lastRowInx, createDateColumn)
{
var urlColumn = createDateColumn-2;
if (ss.getRange(lastRowInx, urlColumn).getValue() == "") // so that subsequent edits to Google Form don't overwrite editResponseURL
{
var form = FormApp.openById('101bMiRw9TQaGbdDc4U_tLAD0QzicqejM9qXOEwJPQKU');
var formResponses = form.getResponses();
var lastResponseIndex = form.getResponses.length-1;
var lastResponse = formResponses[lastResponseIndex];
var editResponseUrl = lastResponse.getEditResponseUrl();
var createEditResponseUrl = ss.getRange(lastRowInx, urlColumn);
createEditResponseUrl.setValue(editResponseUrl);
}
else{} //do nothing
however this seems to break on the getEditResponseUrl. I am getting the following error TypeError: Cannot call method "getEditResponseUrl" of undefined. (line 100, file "Code").
I used #SandyGood 's answer to this post as a reference. I wonder though if her observation about the event trigger is why this is borking. This is the onFormSubmit function I am using to call this and other fucntions.
function onFormSubmit(e)
{
var ss = SpreadsheetApp.getActiveSheet();
var lastRowInx = ss.getLastRow(); // Get the row number of the last row with content
var createDateColumn = ss.getMaxColumns(); //CreateDateColumn is currently in AX (Column 50) which is the last/max column position
var createDate = setCreateDate(ss, lastRowInx, createDateColumn);
var trackingNumber = setTrackingNumber(ss, lastRowInx, createDateColumn);
//var editURL = setEditUrl(ss, createDateColumn);
var editResponseURL = setGoogleFormURL(ss, lastRowInx, createDateColumn);
}//This is the end of onFormSubmit
I also found a whole bunch of sources 234where they were looking use the URL to append to an email, were more complex than my use case, or were unanswered. I also found some solutions for getting the EditURL by binding the script to the form but since I want to store the value on the sheet it needs to be bound to the sheet rather than the form.
UPDATE:
Okay so I tried to bind my script to the form instead of the sheet which allowed me to see the URL but now I have the problem in reverse where the form can't find the spreadsheet methods like .getMaxColumns TypeError: Cannot find function getMaxColumns in object Spreadsheet. (line 40, file "Code") AND .getActiveRange Cannot find method getActiveRange(number). (line 48, file "Code").
Here is the code on the form side
function onFormSubmit(e)
{
var form = FormApp.getActiveForm();
var activeFormUrl = form.getEditUrl();
var ss = SpreadsheetApp.openById(form.getDestinationId());
var createDateColumn = ss.getMaxColumns(); //CreateDateColumn is currently in AY (Column 51) which is the last/max column position
var urlColumn = createDateColumn-1; //urlColumn is currently in AX (Column 50) Calculating using it's relative position to createDateColumn Position
Logger.log(activeFormUrl, createDateColumn, urlColumn);
var checkLog1 = Logger.getLog();
Logger.clear();
if (ss.getActiveRange(urlColumn).getValue() == "") // so that subsequent edits to Google Form don't overwrite editResponseURL
{
var editResponseURL = setGoogleFormEditUrl(ss, createDateColumn, activeFormUrl);
var createEditResponseUrl = ss.getActiveRange(urlColumn);
createEditResponseUrl.setValue(activeFormUrl);
}
else
{
if (ss.getActiveRange(urlColumn).getValue() != activeFormUrl)
{
Logger.log("Something went wrong - URL doesn't match")
Logger.log(ss.getActiveRange(urlColumn).getValue());
var checkLog2 = Logger.getLog();
}
else {}//do nothing
}
}//This is the end of the onFormSubmit function
So I am wondering how I can pass a variable between the form and the sheet. Can I somehow read the form log programmically from the sheet? Can I append the value to the form response array (This would mean a few other edits to the referenced columns but could work). Thoughts #Gerneio , #SandyGood , Anyone else?
UPDATE 2:
There seemed to be a conflict with using both the methods from the FormApp and the SpreadsheetApp within the same function.
The solution that worked for me was to modularize the spreadsheet functions out (except the getActiveSheet) and to leave the getEditResponseURL method within the onFormSubmit Function.
The code snippet can be found posted here.

I'd suggest trying to use the onFormSubmit(e) on the form side.
function onFormSubmit(e)
{
var form = e.source;
var response = e.response;
var sheet = SpreadsheetApp.openById(form.getDestinationId());
var editUrl = response.getEditResponseUrl();
Logger.log(editUrl); // check the logger to see what results you are getting now
// Then do whatever operations you need to do...
}
Update:
I'm not so sure why you are having so many problems with this, but I can tell you for sure that it can be done from either side, the Form or Spreadsheet. I just put together a working example with code written on the Spreadsheet side, none what-so-ever on the Form side. Check it out:
function onFormSubmit(e)
{
var rng = e.range;
var ss = SpreadsheetApp.getActiveSpreadsheet();
var fUrl = ss.getFormUrl();
var f = FormApp.openByUrl(fUrl);
var rs = f.getResponses();
var r = rs[rs.length - 1]; // Get last response made
var c = getCellRngByCol(rng, 'Edit Response URL');
c.setValue(r.getEditResponseUrl());
}
// Specific for a form submit trigger
// Pass e.range and the name of the column
// to return a single cell
function getCellRngByCol(rng, col)
{
var aRng = SpreadsheetApp.getActiveSheet().getDataRange();
var hRng = aRng.offset(0, 0, 1, aRng.getNumColumns()).getValues();
var colIndex = hRng[0].indexOf(col);
return SpreadsheetApp.getActiveSheet().getRange(rng.getRow(), colIndex + 1);
}
There were a few small hiccups that I ran into. Firstly, make sure to setup the trigger accordingly. I highly recommend setting up immediate notifications of failures. Secondly, even though the function will rely on the event that is passed, manually run the onFormSubmit(e) method at least once before submitting a form. It will check to see if your script needs any authorization and will request if needed. I'd also recommend that you open up a new form, link a fresh new spreadsheet, and test this code to make sure it works. Then mold the above code to fit your needs.
If you can't get it, then I'll share a working example.

There seemed to be a conflict with using both the methods from the FormApp and the SpreadsheetApp within the same function.

google appscript form presenting array values for user selection

I'm not sure how to code GAS form buttons to fire a script with dynamic values.
In this scenario, the current sheet cell value is used to Look-Up rows in an adjoining sheet and to populate a result array.
A form then presents a list of buttons containing values from one column of the result array.
Pressing a form button should fire the script postLocationData, and update the current cell and adjoining cells in the row with result array values, and closes the form. At this point, pressing a form button does not seem to do anything. Much thanks in advance for your help :)
function lookUpLocationTest(){
var ui = SpreadsheetApp.getUi();
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getActiveSheet();
var cell = sheet.getActiveCell();
var sheetLocations = ss.getSheetByName('LU_Locations');
var arrayRecords = sheetLocations.getRange(2, 3, sheetLocations.getLastRow(), 2).getValues();
var matchingLocations=[];
for (var i=0;i<arrayRecords.length;i++) {
var result = arrayRecords[i][1].indexOf(cell.getValue())
if(result !== -1) {
matchingLocations.push(arrayRecords[i]);
}
}
if(matchingLocations.length === 0){
var result = ui.alert(
'Message:',
'No Matching Location Found.',
ui.ButtonSet.OK);
return 0;
}
Logger.log(' Process - ' + matchingLocations.length + ' Locations have been found.') ; //matchingLocations is a global
// Prep Form HTML with formatted matching Locations
var HTML= '<form><div>'
for(var i=0;i<matchingLocations.length;i++){
HTML += "<div><input type='button' value='" + matchingLocations[i][1]
+ "' onclick='google.script.run.withSuccessHandler(postLocationData).processForm(this.parentNode)'/></div>";
}
var htmlOutput = HtmlService.createHtmlOutput(HTML).setSandboxMode(HtmlService.SandboxMode.IFRAME);
var result = SpreadsheetApp.getUi().showModalDialog(htmlOutput, 'Matching Locations');
return 1;
}
function postLocationData(lookUpValue) {
var location = lookUpValuesInArray (matchingLocations, 1, lookUpValue); //matchingLocations is a global
var cell = currCell;
var latLongCol = 3;
cell.setValue(location[0][1]);
cell.getRowIndex();
var sheet = cell.getSheet();
sheet.getRange(cell.getRowIndex(), latLongCol).setValue(location[0][0]);
var temp =1;
}

The function "google.script.run" will be executed on the client side but it will call a function on the serverside (your .gs file). In this case the function you will call is "processForm()" where you are sending "this.parentNode" as parameter.
In you Apps script file (gs file) you should have a function called "processForm()" you didn't post it in the example.
After this function ends, if everything went well, the function "google.script.run" will execute the function that you defined in "withSuccessHandler()". In you example you used "postLocationData".
This function will receive as parameter the results returned from the execution of processForm().
As I mentioned before google.script.run is called on the client side, therefore the function that will be executed if everything went well (the one contained in withSuccessHandler), has to be also in the client side. This means it has to be part of the script contained in the HTML.
As the way you posted the code, I would change the onclick to:
onclick='google.script.run.withSuccessHandler(someJavascriptFunction).postLocationData(this.parentNode)
withSuccessHandler is optional, if you decided to use it, then you should create a html script tag in you HTML variable having that javascript function to show an alert or something that tells the user the result of clicking the button.
You can also create an html file in the appsscript project and call it like: HtmlService.createHtmlOutputFromFile('Index').setSandboxMode(HtmlService.SandboxMode.IFRAME);
This way you can have a cleaner html file and the javascript asociated to it.
Hope this helps.

Google Script: Format URL in Array.Push

I have a working script that upon form submit, specific rows move from one sheet to another. One of the fields I'm pushing is a url.
On the second sheet, the link is listed and it is hyperlinked, but it's really ugly and I really want to format it so that it shows "Edit" with a hyperlink. I've tried a number of ways, but my knowledge is limited so all I get are errors. I'm hoping someone can point me in the right direction.
Here is my code. I'm very new at this so the script is not at all sophisticated. Any help/suggestions would be appreciated!
function copyAdHoc(){
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sh = SpreadsheetApp.setActiveSheet(ss.getSheetByName("Form Responses 1"));
var data = sh.getRange(2, 1, sh.getLastRow() - 1, sh.getLastColumn()).getValues();
// Grab the Headers from master sheet
var headers = sh.getRange(1,1,1,sh.getLastColumn()).getValues();
var date = headers[0].indexOf('Effective Date');
var name = headers[0].indexOf('Employee Name');
var loc = headers[0].indexOf('Location');
var issue = headers[0].indexOf('Description/Question/Issue');
var add = headers[0].indexOf('Additional Information');
var change = headers[0].indexOf('Is this a Qualifying Life Event?');
var url = headers[0].indexOf('Form URL');
var category = headers[0].indexOf('Primary Category');
var status = headers[0].indexOf('Current Status');
var users = headers[0].indexOf('Users');
// Grab only the relevant columns
for(n = 0; n < data.length; ++n ) { // iterate in the array, row by row
if (data[n][change] !== "Yes" & data[n][category] !== "Employee Relations" & data[n][date] !== "") { // if condition is true copy the whole row to target
var arr = [];
arr.push(data[n][url]);
arr.push(data[n][users]);
arr.push(data[n][date]);
arr.push(data[n][loc]);
arr.push(data[n][name]);
arr.push(data[n][category]);
arr.push(data[n][issue] + ". " + data[n][add]);
arr.push(data[n][status]);
var sh2 = SpreadsheetApp.setActiveSheet(ss.getSheetByName("Ad Hoc")); //second sheet of your spreadsheet
sh2.getRange(sh2.getLastRow()+1,2,1,arr.length).setValues([arr]); // paste the selected values in the 2cond sheet in one batch write
}
}
}

It's a bit messy but the only way I know to achieve what you're trying to do would be to insert a column to the left of the hyperlink with the word Edit right justified and then remove the borders between the two.

From your description I am assuming you want the word "Edit" to be Hyperlinked. To do so, try this:
function getHyperlink(url)
{
return "=HYPERLINK(\""+url+"\","+"\"Edit\""+")";
}
function mainFunct()
{
//Do necessary steps
var tarLink = "https://www.google.com";
var tarRng = tarSheet.getRange(rowNum, colNum).setValue(getHyperlink(tarLink));
//perform other steps
}
EDIT:
Forgot to mention, since you're pushing your values to the array... you can do it in a similar way by either just storing the hyperlink in a variable or directly pushing it to the array like all the other values. Or if you're dealing with a hyperlink that has a static and dynamic part, For example: https://stackoverflow.com/questions/post_id, where post_id keeps changing but most of the URL is static, you can easily handle it by just passing the post_id to the getHyperlink function and getting the required Hyperlink in return. Hope this helps.

Append a number if name is already used?

In Javascript, I have a script that allows me to upload files to my server, then retrieve the output. One component of the output is the name of the file that was uploaded. For example, an output name might look like this:
test.pdf
The contents of test.pdf are then saved to a localStorage key, with the item name being the name of the file: localStorage.setItem(name, data).
This works fine, but not when the name of the file is the same as the name of a file that is being uploaded and retrieved.
What I mean by this is that if the user uploads a file with the name Hello 34.pdf, it will save the name of that file and the contents to a LS key. If they upload the same file again, however, or a different file with the same name, then it will replace the current file with the same name.
To remedy this, I need to be able to append a number to the end of the document title, so that you can have as many versions of the file with the same name in LS.
I know I can check to see if the file has the same name as one already uploaded like this:
var title = $('#file')[0].files[0]["name"];
if (localStorage.getItem(title)) {
alert("same name");
}
localStorage.setItem(title, data);
But from there I can't figure out how to add a number to the end. I don't think regex is an appropriate way to do this, as this:
if (title.match(/[\.pdf ]\d/g) != null) {
var number = title.match(/[\.pdf ]\d/g) + 1;
} else {
var number = "1";
}
Is dependent on the .pdf extension to be at the end, and JS regexes are generally bad.
Are there better ways to do this? Should I be indexing the file names a different way?

Since localStorage stores all items as strings it is up to you as the developer keep track of the keys used to index that data. The actual file, when uploaded, will not be duplicated; only the key will be duplicated.
That said I would just append a unique ID for each file uploaded like so:
fileName = test.pdf
fileKey = test.pdf#1
Then store the file name in local storage as a key and the value would be the "version" you are up to now such as:
localStorage.setItem("test.pdf", "1");
Then you can increment that value for each new revision and obtain the key easily for the next revision and store the file in local storage like so:
localStorage.setItem("test.pdf#1", "file data here");
Does that make sense?
EDIT (an example):
-- To store the data:
var title = $('#file')[0].files[0]["name"];
var revNo = 1;
if (localStorage.getItem(title)) {
revNo = localStorage.getItem(title);
revNo++;
}
localStorage.setItem(title, revNo);
localStorage.setItem(title + "#" + revNo, data);
-- To retrieve the data:
var title = $('#file')[0].files[0]["name"];
var revNo = 1;
if (localStorage.getItem(title)) {
revNo = localStorage.getItem(title);
}
// get the latest revision
var data = localStorage.getItem(title + "#" + revNo);

You may have more than 2 files with the same name
var title= $('#file')[0].files[0]["name"];
if(localStorage.getItem(title)){
var n= 1;
while(localStorage.getItem(title+n)) n+= 1;
title= title+n;
}
localStorage.setItem(title, data);

Can't you store the files within an array? Something like this (freehanded):
if (localStorage.getItem(title)) {
var files = JSON.parse(localStorage[title]);
files.push(data);
localStorage.setItem(title, JSON.stringify(files);
} else
localStorage.setItem(title, JSON.stringify([data]));

If you did decide to go via the RegEx route, this would find a number at the end of the title string then increment it by 1 -
var title = "hello.pdf1"
if (title.match(/(\d+)$/)) {
var number = parseInt(title.match(/(\d+)$/)[1],10) + 1;
} else {
var number = "1";
}
