A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
I had to create an acct here just to reply in hopes I could help others with this error as it was driving me nuts.
There is one solution I have not seen suggested, that I determined I could reproduce 100% of the time for the messagebox error of "Microsoft Excel cannot paste the data" either between workbooks, worksheets, or even within the same worksheet.
I wonder how many of these folks have clipboard managers/enhancers running? Even though there is no legitimate reason a simple paste even of unformatted cells of only values would still result in the above error, but in my case having CLIPJUMP running and simply maintaining clipboard history of multiple entries, a simple single data item paste from Excel, to Excel, results in this Excel error.
My clipboard manager <tries> to grab formatting, as do many others, which is why I believe some posted workarounds involving pasting into another app and back have helped.
So, even though they may not ever conflict with anything.....disable <anything> that touches the clipboard in <any> way, and from what I can tell that will solve many occurrences of this error since different clipboard managers/enhancers have become more and more common.
Simply shutting down my clipboard manager for the time I use Excel has 100% eliminated this error.
