XLSX to CSV Converter
Upload an Excel or OpenDocument spreadsheet and download CSV output for spreadsheets, databases, scripts, and reporting workflows.
Use the Excel to CSV converter when your source file is an XLSX, XLS, or ODS workbook.
A workbook with one worksheet downloads as a plain CSV file.
Each worksheet becomes its own CSV file inside one ZIP download.
CSV files use comma delimiters, quoted fields, UTF-8, and line breaks compatible with common spreadsheet tools.
Excel exports
Turn workbook data into CSV files for import into databases, data tools, and automation scripts.
ODS compatible
OpenDocument spreadsheets from LibreOffice and other office suites use the same conversion path.
No output limits
The tool preserves workbook data in CSV form and keeps the normal 1 GB upload limit.
