How to Convert Excel to CSV

Quick answer: Export an Excel sheet to CSV for imports, scripts, and data pipelines. Open Excel 转 CSV — everything runs locally in your browser, and files never leave your device.

Steps

1. Upload the .xlsx to the Excel to CSV tool.
2. Select the sheet and separator (comma, semicolon, or tab).
3. Pick encoding: UTF-8 for programs, UTF-8 with BOM if Excel will reopen it.
4. Download the .csv.

Important notes

• Only the selected sheet is exported — multi-sheet workbooks need one pass per sheet.
• Formulas export as their calculated values, and dates export in their displayed format, so standardize date columns first.
• European systems often expect semicolon separators because they use commas as decimal marks.

Common questions

Why does Excel show my CSV as garbled text? A BOM-less UTF-8 file with Chinese characters gets misread as ANSI — export with BOM for Excel.

Can I keep multiple sheets in CSV? No, CSV is a single-table format.
