The following script will hide any rows on a sheet if Col Q has "YES" in it.

function AutoHidingTechnique() {
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
  sheet.showRows(1, sheet.getLastRow());
  var range = sheet.getRange("Q1:Q" + sheet.getLastRow());
  var values = range.getValues();
  var numRows = range.getNumRows();

  for (var i = 0; i < numRows; i++) {
    if (values[i][0] === "YES") {
      sheet.hideRows(i+1);
    }

The script used to work perfectly (for months) on an hourly time-driven trigger.

Lately the execution log affirms the script is still working fine, but the rows are not being hidden anymore.

When I run the script manually, however from the menu or editor, it does hide the rows.

The fact that the time-driven script used to work perfectly and the script still works perfectly when ran manually leaves me at a loss as to how get the time-driven hourly trigger to actually do what it says it is doing.

Why is that and how can I fix it?

• 1 When run from a trigger the active sheet is Spreadsheet.getSheets()[0]. – Cooper Commented Feb 1 at 0:53
• 1 @Cooper's statement is correct. You may debug what's going on by having a console.log(sheet.getName()); to see which sheet is being returned as the trigger runs. Try changing getActiveSheet() to getSheetByName(name) to see if that works. – Saddles Commented Feb 1 at 1:11
• Thanks @Cooper and @Saddles! It's working again properly now. :) – sbradd Commented Feb 1 at 2:40

When we use trigger the active sheet is Spreadsheet.getSheets()[0] to make things work as intended to use the specific sheet that we wanted we need to specify what sheet were gonna use by using getSheetByName(name) instead of getActiveSheet().

var sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet(); // returns the first sheet of the spreadsheet.

var sheet = SpreadsheetApp.getActive().getSheetByName(name); // returns the specific sheet of the spreadsheet.
