How to choose
Inside Excel or an upload
An add-in works in the workbook you have open. A chat or web app takes a copy of the file, so you bring the result back yourself.
What it does
Writing formulas, analyzing and charting, editing the workbook, or cleaning the data are different jobs. Most tools do one or two of them well.
What the AI reads
Some AI tools send the rows they work on to a language model; others work from a summary or a sample. Check which, especially for customer lists.
Price and plan needed
Some need a Microsoft 365 or Google Workspace plan first; others charge per message, credit or cell. Price a month of real use.
