No. All editing happens in your browser. Your original CSV file remains unchanged. Download creates a new file with only your selected columns in the chosen order.

CSV fields enclosed in quotes are properly preserved. Commas, newlines, and quotes within quoted fields remain intact during column reorganization. Follows RFC 4180 specification.

Use the Reset button to restore original column order and names. Alternatively, reload your CSV file to start fresh. Browser-based processing means no permanent changes until you download.

All cell values are preserved exactly as they appear in the original CSV. Numbers, dates, and text remain unchanged. The editor only modifies column order and header names.
