Chat With CSV: AI Answers for CSV and Excel Files
Chat with a CSV or Excel file in plain English and get SQL-backed answers with charts. Your file stays in the browser; the AI writes the SQL and every chart shows it.

AskCSV is not a ChatGPT clone. It turns a question into read-only SQL over the file open in your browser and shows the query behind every chart.
A SQL-backed option for spreadsheet questions
If you want to ask plain-English questions about spreadsheet data, you have two reasonable options: paste the file into a chat assistant, or use a tool built for tabular questions. AskCSV is the second kind. Your question becomes a read-only SQL query that runs in your browser over the whole file, the totals and trends are computed in code from the result, and the generated SQL is displayed with each chart.
That matters for spreadsheet work because the answer is often a number someone will act on. A visible query lets you check the measure, filters, and grouping rather than trusting prose.
What happens to your file
The file is opened in your browser and stays in this site's storage for your account or guest session; it is not uploaded. Files and chats stay until you delete them or clear the site's data, and you can delete any file or chat at any time. AskCSV keeps what the AI sees to a minimum: to write the SQL and explain the result, the AI provider (OpenAI) gets only your question, the file's name and row count, the columns you chose to share with up to 10 sample rows, up to 100 rows of each query result plus summary figures, and the earlier messages in the chat — never the file itself. See what happens to your data.
What file should you use?
AskCSV accepts .csv, .tsv, delimited .txt, Excel .xlsx (every sheet), and pasted delimited data. From Google Sheets or Numbers, export the sheet as CSV first, and save older .xls files as .xlsx or CSV.
- Add the sheet you want to analyze — as
.xlsx,.csv, or.tsv. - Open AskCSV at / in any browser — nothing to install.
- Open the file or paste delimited cells.
- Ask a question such as "What were total sales by month?"
