Free private AI chat for Excel & CSV

How PrivateExcelChat works

PrivateExcelChat is a free private AI chat for Excel and CSV. Upload a spreadsheet, ask questions in chat, and get short plain-language answers about your own numbers. No account is required. Ads keep the product free.

Use it in four steps

  1. Choose one Excel (.xlsx) or CSV file, up to 10 MB. That file becomes the only dataset for this visit.
  2. Pick which sheets to load. Each selected sheet is prepared so chat can answer from those columns.
  3. Ask in chat: totals, comparisons, top rows, missing values, or anything the loaded columns can support.
  4. Read a short answer. We do not show SQL or internal query steps. If the sheet does not contain enough to answer, we say so.

What happens to your file

We process the upload on our server for this session so chat can read your data. That is what “private” means here: session-private, not “never leaves your device.” Do not upload data you are not allowed to process with a third-party AI.

Session tables are deleted when you click Clear my data, refresh or leave the page, or sit idle for about 30 minutes. The next visit starts empty.
