CSV Editor - Modify Data Locally
Edit CSV files directly in your browser. Our Free CSV Editor provides a spreadsheet interface that runs locally, ensuring your sensitive data is never uploaded.
What is the CSV Editor?
Making a quick change to a database export or mailing list shouldn't require launching a heavy desktop application or uploading sensitive customer data to a cloud service. This CSV Editor provides a lightweight, interactive spreadsheet interface right in your browser. You can upload a file locally, double-click any cell to edit the text, add new rows, and instantly export the updated file. Because we prioritize data privacy, the entire editing process utilizes client-side DOM manipulation. Your CSV file is modified securely in memory and never touches an external server.

Frequently Asked Questions
No, because data is processed purely in local memory for privacy, you must manually click 'Export' to save your changes before closing the tab.
Absolutely not. The file parsing, editing, and exporting are all handled natively by your web browser.
The parser correctly handles standard CSV quoting (e.g., "Smith, John") to ensure commas inside cells don't break the columns.
All file processing is performed locally in your web browser. We do not upload, store, or view your data.
