CSV Editor

Edit CSV files directly in your browser. Inline cell editing, sort columns, filter rows, add/delete rows and columns, and export to CSV, TSV, or JSON. All processing client-side — your data stays private.

✓ Inline cell editing ✓ Sort & filter columns ✓ Export CSV / TSV / JSON ✓ Client-side only

Frequently Asked Questions

Can I edit large CSV files?▼

Yes. The editor handles CSV files up to thousands of rows. For very large files (100k+ rows), paste a representative sample to avoid browser memory limits.

What delimiters are supported?▼

Comma (,), tab (\t), semicolon (;), and pipe (|) are all supported. The editor auto-detects the delimiter when you paste data.

Does the editor send my data anywhere?▼

No. All processing is entirely client-side in your browser. Your CSV data never leaves your device.

Can I add or delete rows and columns?▼

Yes. You can add rows at the bottom, insert columns, delete selected rows, and reorder columns by dragging the headers.

What export formats are available?▼

You can export your edited data as CSV (comma-separated), TSV (tab-separated), or JSON array of objects.
