Insert column at very end with blank cells in between

Question

I am having an issue with inserting a column after my last column. I am using the below code, but I have blanks all throughout my data so it is inserting a column about halfway through. It is confusing because row 1 is completely full all the way until the end so I figured that would trump the blank cells throughout, but it is still inserting a column halfway through.

function AddColumn() {
  var ss = SpreadsheetApp.openById("spreadsheetId");
  var sheet2 = ss.getSheetByName("sheetName");
  sheet2.insertColumnAfter(sheet2.getLastColumn());
}

Thank you for any help!

Answer 1

It's not the best way but

function AddColumn() {
  var ss = SpreadsheetApp.openById("spreadsheetId");
  var sheet2 = ss.getSheetByName("sheetName");
  sheet2.insertColumnAfter(sheet2.getDataRange().getValues()[0].length);
}
