Export a new Excel or CSV file. Your source file stays exactly where you left it.
What should I know before exporting?
This is a data extraction tool. Exports contain displayed values, not original formulas, charts, styles or macros. Empty or duplicate rows are removed only when selected. CSV exports prefix formula-like text with an apostrophe to keep it from executing in spreadsheet apps. Limits: 20,000 rows, 100 columns and 200,000 cells per worksheet.
How is my data handled?
Files are parsed locally and are not uploaded. Clearing the workspace or closing the tab removes its data. If you use Ask AI, the text you type is sent to Cloudflare Workers AI; the spreadsheet is not included. Cloudflare hosts this website and processes standard connection information.
