Excel to CSV Converter

About the Excel to CSV Converter

Use this tool to convert Excel spreadsheets (.xlsx, .xls) into clean CSV (Comma-Separated Values) text that you can import into databases, analytics tools, CRMs, marketing platforms, or any system that accepts CSV files.

Key Features

• Excel file support: Works with both modern .xlsx and legacy .xls workbooks.
• Header row option: Keep or ignore the first row as column headers.
• Automatic CSV generation: Uses the robust sheet_to_csv logic from the Excel file for correct quoting and escaping when headers are enabled.
• Simple output for raw data: When headers are disabled, rows are joined into CSV manually for straightforward export.
• Copy & download: Copy the CSV to your clipboard or download a .csv file in one click.
• Local processing: Conversion happens entirely in your browser—no upload, no server-side storage.

How to Convert Excel to CSV

1. Upload your Excel file: Click the upload area or drag and drop a .xlsx / .xls file from your computer.
2. Choose header settings: If your first row contains column names, keep "First row is header" checked so the CSV includes a header row.
3. Wait for automatic conversion: The tool reads the first worksheet and converts it to CSV text.
4. Review, copy, or download: Check the output in the text area, then copy or download the CSV file.

Example: Excel to CSV

Example Excel table:

• Row 1: id, name, email

id,name,email
1,Alice,alice@example.com
2,Bob,bob@example.com

You can now import this CSV into tools like Excel, Google Sheets, Power BI, Tableau, PostgreSQL, MySQL, BigQuery, and many others.

FAQ – Excel to CSV Converter

Which sheet is converted to CSV?

The tool converts the first worksheet in your Excel file. If you need a different sheet, move it to the first position in Excel before uploading.

How are commas, quotes, and newlines handled?

When headers are enabled, the tool relies on Excel's CSV utilities to properly escape values that contain commas, quotes, or line breaks, following standard CSV conventions.

Is there a row limit?

There is no hard-coded row limit in the tool itself, but very large files can be slower to process in the browser. For huge datasets, consider splitting your file into smaller chunks.

Is this Excel to CSV converter free and private?

Yes. The converter is free to use, requires no account, and processes your data locally in your browser, so your spreadsheets stay private.
