How to convert Excel to CSV online - free and no software needed

The CSV format is the standard import format for most management systems, databases and analysis tools. When you need to import data from an Excel spreadsheet into an ERP, CRM, email marketing system or database, CSV is almost always the accepted format. This tool converts any sheet from an .xlsx or .xls file into a .csv file in seconds.

You can choose which sheet to export - useful when the file has multiple sheets and you only need one. You can also select the delimiter: comma (international standard), semicolon (Brazil/Europe standard) or tab (used by some legacy systems). Choose the delimiter that the destination system expects to avoid import errors.

The tool generates CSV in UTF-8 encoding, the modern standard accepted by the vast majority of current systems. The file is downloaded directly to your device - no data is sent to servers.

To use, upload your Excel file, select the sheet and delimiter, and click "Export as CSV". The download starts automatically.
