About the Excel to CSV Converter
Convert an Excel sheet (XLSX/XLS) into a plain CSV file that any system can read — databases, analytics tools, e-commerce imports and more. It runs entirely in your browser, so your data stays private.
How to use it
- Drop your Excel file onto the box, or click to browse.
- Click Convert to CSV.
- The first sheet is exported as comma-separated values.
- Download the .csv file.
Many tools only accept CSV uploads. Use this to turn an Excel sheet into a clean CSV for importing contacts, products or records — all locally in your browser, so nothing is uploaded.
Frequently asked questions
Which sheet gets converted?
The first worksheet in the workbook is exported to CSV. Re-order your sheets in Excel if you need a different one.
Will my numbers and dates stay correct?
Cell values are exported as text/values exactly as stored. Check date formats after import, as CSV has no formatting.
Is my file uploaded?
No. The conversion happens entirely in your browser, so your data never leaves your device.
Does it handle commas inside cells?
Yes — values containing commas or quotes are properly escaped per the CSV standard.
