What is Excel to CSV?

Excel to CSV converts XLSX and XLS spreadsheets into comma-separated values (.csv) files. CSV is the universal data interchange format — accepted by every database, data tool, and programming language.

How It Works

Drop your Excel file. SheetJS reads every sheet and converts the cell data to CSV format. If the workbook has multiple sheets, each is exported as a separate .csv file. Everything runs in your browser — nothing is uploaded.

How to Use

  1. 1

    Upload your Excel file

    Drop an XLSX or XLS file onto the upload zone.

  2. 2

    Select sheet

    If the workbook has multiple sheets, choose which one to export as CSV.

  3. 3

    Choose delimiter

    Select comma, semicolon, or tab as the column separator in the output CSV.

  4. 4

    Convert

    Click "Convert to CSV". The sheet data is exported as a plain text CSV file.

  5. 5

    Download

    Save the .csv file to import into databases, data analysis tools, or other applications.
