Looking for ChatGPT CSV or ChatGPT Excel?
Ask plain-English questions about CSV or TSV exports with on-device AI. Analysis content stays in your browser, with no sign-up required to start.
AskCSV is not a ChatGPT integration. It uses an on-device AI model to analyze CSV or TSV exports inside a compatible browser.
A local alternative for spreadsheet questions
If you want to ask plain-English questions about spreadsheet data, you do not have to send the file to a cloud chatbot. AskCSV reads a CSV or TSV export in your browser, turns your question into a local query, and displays a calculated answer or chart.
CSV rows, questions, SQL, results, charts, and chats are not sent to AskCSV or a cloud AI provider. The app and on-device model still require network downloads, and the first analysis may download about 1.8 GB. Supported browsers can cache the model for later visits.
What file should you use?
AskCSV supports .csv, .tsv, and pasted delimited data. It does not directly open Excel .xlsx workbooks. If your data is in Excel, Google Sheets, or Numbers, export the relevant sheet as CSV or TSV first.
- Export the sheet you want to analyze as
.csvor.tsv. - Open AskCSV in a compatible WebGPU browser.
- Load the export or paste delimited cells.
- Prepare the on-device model if needed.
- Ask a question such as "What were total sales by month?"
What AskCSV provides
- Plain-English questions without writing formulas or SQL
- Calculated tables and charts when the data and question support them
- 10 successful Free analyses per month with no account required
- Pro at $5/month for unlimited successful analyses, result exports, deterministic two-file join or stack, and no ads
Results can be inaccurate or incomplete, so verify important calculations before relying on them.
Try the local workflow
Load a CSV or TSV export you are authorized to use and ask your first question. Free analysis needs no sign-up, and the analysis content stays in your browser.
