Hi @Kashif Bashir Bhatti , I believe the custom function is clearing the undo/redo stack, so there is nothing to be undone. This is why the button is grayed out/disabled. AFAIK, there is no workaround.
Undo button disabled after Custom Functions in Excel

Hi,
I am working on an Excel Add-in in Javascript and have written some custom functions in it. Now Problem I am facing is that when user writes custom function in a cell, Undo and Redo buttons are disabled and user cannot undo its action or some previously made change.

2023-01-02T12:27:30.28+00:00 Is there any to avoid this clearing of undo/redo stack? As I am not doing this explicitly, I only call my API and return the result or in some cases make simple calculations which should not clear any stack.
