How to Convert Excel to CSV Free — XLSX to CSV Online

Why Convert Excel to CSV?

CSV is the universal data format. Every database, programming language, analytics tool, and spreadsheet app reads CSV. Excel files (.xlsx) are proprietary and require specific software to open. Converting to CSV makes your data portable, importable, and future-proof.

How to Convert Excel to CSV

1. Open the Excel to CSV tool
2. Drop your .xlsx or .xls file onto the page
3. Select which sheet to convert (if multiple sheets exist)
4. Download the CSV file

The conversion happens entirely in your browser. Your spreadsheet data is never uploaded to any server.

Common Use Cases

• Database imports — most databases accept CSV for bulk data loading
• Data analysis — Python (pandas), R, and other tools prefer CSV input
• CRM uploads — Salesforce, HubSpot, and others import contacts via CSV
• Email list imports — Mailchimp, ConvertKit, and email platforms use CSV
• Cross-platform sharing — CSV opens everywhere, Excel doesn't

Handling Multiple Sheets

Excel files can contain multiple sheets. CSV is a flat format — one file, one sheet. When your Excel file has multiple sheets, the tool lets you pick which sheet to export. Need all sheets? Convert each one separately to get individual CSV files.
