Google Scripts external spreadsheet data validation

Question

I was interested in automating data validation of a Google Spreadsheet against another Google Spreadsheet using Google Scripts. I can't seem to find a way to reference the range of another spreadsheet using the openById method. Any thoughts?

 function externalSheetDataValidation() { var cell = SpreadsheetApp.getActiveRange(); //var dataValidationSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("dataValidationRules"); //var dataValidationSheet = SpreadsheetApp.openByUrl("https://docs.google.com/spreadsheets/d/10Z2s1bSRIhZzBBrMfPmhEphnPx-kJdV3LLlbv0L59g8/edit#gid=0"); var dataValidationSheet = SpreadsheetApp.openById("10Z2s1bSRIhZzBBrMfPmhEphnPx-kJdV3LLlbv0L59g8"); var sheet = dataValidationSheet.getSheets()[0]; var range = SpreadsheetApp.getActiveSheet().getRange("A3:A4"); var rule = SpreadsheetApp.newDataValidation() .requireValueInRange(range, true) .setAllowInvalid(false) .build(); cell.setDataValidation(rule); Logger.log(dataValidationSheet.getName()); } 

Answer 1

If I am understanding correctly, the issue you are having is selecting a data range from an external spreadsheet? Im assuming dataValidationSheet is supposed to be the external sheet. It looks like you were on the right track. It looks like the issue is that you are expecting the sheet to be active once you grab it. Try this change: var range = sheet.getRange("A3:A4");
Currently you are grabbing the external sheet, but then getting the range from the sheet that was already active. Hopefully this helps!
