I read that google spreadsheets have a column limit of something like 20000. However my spreadsheet does not have any column beyond AC.

How can I add columns to my spreadsheet?? (in Excel this is automatic)

You can insert more columns in the Insert menu.

If you need to insert more than one column, you can highlight a number of columns and it'll prompt to insert that amount:

High Quantity Method

If you need a huge amount of columns inserted, open a text editor, create a large quantity of TAB characters, and copy into Google Sheet.

Google Sheet will interpret each tab as a column so it'll quickly create new columns based on the number of tab characters you have pasted.


You can go up to column ZZZ, which is exactly 18,278 columns following @Nelson 's process

enter image description here

[EDIT:] You can use the script below to add a specific number of columns

function userAddColumns() {
  var spreadsheet = SpreadsheetApp.getActive();
  var ui = SpreadsheetApp.getUi();
  var result = ui.prompt("How many columns do you want to add?");

  spreadsheet.getActiveSheet().insertColumnsAfter(spreadsheet.getActiveRange().getLastColumn(), result.getResponseText());

  • Yes, but it seems like a painfully slow process to go till zzz... no? Commented Oct 27, 2021 at 23:21
  • Updated my answer with an alternate method.

  • @KansaiRobot I've added a script. When you run it will prompt you how many columns you want to add.
