3 Ways to Input CSV Data
Use file selection, drag and drop, or pasted delimited data to load a CSV, TSV, or Excel file into AskCSV.
Load CSV, TSV, or Excel data by selecting a file, dragging it onto the page, or pasting delimited cells. All three methods open the data in your browser, where it stays; the file is not uploaded.
Click to select
Click the file area to open your browser's file picker, then choose a .csv, .tsv, or .xlsx file from your device. AskCSV opens it in this browser and keeps it in this site's storage for your account or guest session.
Drag and drop
Drag a .csv, .tsv, or .xlsx file onto the file area. This uses the same path as file selection.
Paste from the clipboard
Copy delimited rows from a website, Excel, Google Sheets, Numbers, or another spreadsheet tool, then paste them into AskCSV. Pasting cells is supported, and Excel .xlsx workbooks open fine — AskCSV reads every sheet.
Where your data goes
Rows, questions, generated SQL, results, charts, and chats are stored in this browser for your account or guest session, and questions are answered with read-only SQL over your local file. 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. Optional sign-in, billing, and analytics follow the choices described in the Privacy Policy; there is no advertising.
Guest credits expire 7 days after they are issued. Files and chats stay in this browser until you delete them or clear the site's data, and you can delete any file or chat at any time. How large a file can be handled depends on the browser and device.

AskCSV opens your CSV or Excel file in your browser, runs read-only SQL over it there, computes results deterministically, and shows the generated SQL with every chart.
