Convert Excel to CSV online
Convert XLSX to CSV when you need spreadsheet data in a plain-text format for databases, imports, scripts, analytics tools, or simple data exchange.
When should you convert Excel to CSV?
- Export table data for apps that accept CSV imports
- Move spreadsheet rows into scripts or databases
- Share a lightweight data file without workbook features
- Use one sheet's values in tools that do not read XLSX
Before you convert
CSV stores values, not workbook features
Formulas, styling, charts, multiple sheets, merged cells, and filters are not preserved as spreadsheet features.
Check separators and encoding
Most apps accept UTF-8 CSV, but some regional tools expect a different delimiter or import setting.
