I am trying to remove older duplicate form responses based on a column using the following code.
The credit for the code goes to: http://www.jacorre.com/tutorial/remove-duplicate-rows-google-spreadsheets/
The code in my script is:
function removeDuplicates() {
var ss = SpreadsheetApp.getActiveSpreadsheet(),
responses = ss.getSheetByName('Name of Source Sheet'),
range = responses.getDataRange(),
numRows = range.getNumRows()-1,
data = range.getValues(),
columnHeadings = [data[0]],
newData = [];
for (var i=numRows; i>0; i--) {
var row = data[i],
duplicate = false;
for (var j in newData) {
if (row[4] == newData[j][4]) {
duplicate = true;
}
}
if (!duplicate) {
newData.push(row);
}
}
var final = ss.getSheetByName('Name of Destination Sheet');
if (!final) {
var final = ss.insertSheet('Name of Destination Sheet');
}
final.clearContents();
final.getRange(1,1,1,columnHeadings[0].length).setFontWeight('bold').setValues(columnHeadings);
final.getRange(2, 1, newData.length, newData[0].length).setValues(newData);
}
This has been set to trigger on Form Submit. It works well on new form submissions.
However, when an existing response is edited using 'Form Edit URL' from: Show URL used to edit responses from a Google Form in a Google Spreadsheet by using a script the values are not updated into the new sheet.
But if the function is run manually the updated row is updated to the new sheet.
How can I sort this problem? Any help will be appreciated. Thank you.
