A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Is there a specific error message you ran into?
which Claude add-in did you use? You need specifically the "Claude for Microsoft 365"; do not use the Claude by Anthropic for Excel, or the connector, which will only want Microsoft work/school account.
If you can tell me if you ran into any error, what it says, that will help a lot.
