I am trying to identify if a cell's data was copy or pasted in an excel sheet within a React Excel Add-in. To do this I found that this can be done in VBA using undo stack: Excel VBA How to detect if something was pasted in a Worksheet
However, same interfaces are not present in React. Is there any way to access the undo stack in Excel's React add-in?
In Excel web add-ins you can use the onChanged event of a worksheet. Event handlers for the onChanged event receive a WorksheetChangedEventArgs object when the event fires.
The WorksheetChangedEventArgs object provides information about the changes and the source. Since onChanged fires when either the format or value of the data changes, it can be useful to have your add-in check if the values have actually changed. The details property encapsulates this information as a ChangedEventDetail.
