CSV → Excel

Paste or upload CSV/TSV and get an Excel (.xlsx) file — your data never leaves the browser

On-Device

1. Paste data

Comma, tab, and semicolon delimiters are detected automatically. Pasting a table copied from Excel works too.

3. Convert

Paste CSV/TSV data or upload a file and get an Excel (.xlsx) workbook. Delimiters (comma, tab, semicolon) are detected automatically; numbers become numeric cells and the first row becomes a bold header, so the sheet is ready to use. Nothing is sent to a server.

What you can do

✓Automatic delimiter detection (comma, tab, semicolon)
✓Handles quoted fields and line breaks inside fields
✓Auto numeric cells, bold header, auto column widths
✓Preview table before converting
