Features
Sheets out, CSV in one pass
Drop an .xlsx file, convert, download .csv. Built for imports, scripts, and databases.
Quoted, Excel-friendly CSV
Commas and quotes are escaped. A UTF-8 BOM so Excel opens it without mojibake.
No empty-file trap
If the workbook has no tables, you get a plain-language empty state — we never drop a blank CSV on you.
Multiple tables, one file
Each detected table is written in order, separated by a blank line so you can split them later.
100% private, in the browser
The workbook never leaves your device. Conversion runs in this tab — no account required for the first run.
Zero server upload
Bytes stay in browser memory. We never see the spreadsheet or the CSV you download.
No watermark
The CSV is yours — no extra header row, no branded column.
Any modern browser
Chrome, Firefox, Safari, Edge — desktop or phone. No plugin, no install.
