Excel to CSV Converter
Convert your Excel (.xlsx) files to CSV format. Choose delimiter, encoding, and other options.
About the Excel to CSV Converter
The Excel to CSV Converter turns an .xlsx workbook into a plain CSV file, the universal format that nearly every system, database, and script can read. When a tool won’t accept Excel but will take CSV, this is the bridge.
CSV is the lowest common denominator for tabular data: lightweight, text-based, and accepted by import tools everywhere. Converting Excel to CSV lets you feed your data into databases, analytics platforms, and code that don’t understand the Excel format.
Conversion happens in your browser, so your spreadsheet never leaves your device. That keeps sensitive figures private, with options for delimiters and quoting, and no upload or account needed.
How to use the Excel to CSV Converter
- Upload the Excel (.xlsx) file you want to convert.
- Select the sheet to export if the workbook has more than one.
- Set delimiter and quoting options if needed (for example comma or semicolon).
- Convert the sheet to CSV.
- Download the resulting CSV file.
Common use cases
- Preparing spreadsheet data for import into a database or CRM.
- Feeding data into a script or tool that only reads CSV.
- Creating a lightweight, shareable version of an Excel sheet.
- Exporting one sheet from a multi-sheet workbook as CSV.
Frequently asked questions
What happens to multiple sheets?
CSV holds a single table, so you export one sheet at a time. Choose the sheet you need, and run the converter again for others.
Can I choose the delimiter?
Yes. You can select the separator (such as comma or semicolon) and quoting behavior to match what the destination system expects.
Will formulas be exported?
CSV stores values, not formulas, so each cell’s computed result is written out. The underlying formulas are not preserved in a CSV.
Is my spreadsheet uploaded to a server?
No. The conversion runs in your browser, so your data never leaves your device.
How do I convert the other way?
Use the CSV to Excel converter to turn a CSV back into an .xlsx workbook.
