Since processing is client-side, we recommend files under 10MB or 100K rows. For very large files, the browser may slow down. The tool shows a row count preview before processing — you can limit comparison to the first N rows if needed.
Results are categorized into three types: Added rows (green, only in file B), Removed rows (red, only in file A), Modified rows (yellow, same position but different content). Filter by type to focus on specific changes.
Comma, semicolon, tab, and other common delimiters are supported with auto-detection. Quoted fields, escaped newlines, and standard CSV features work correctly. UTF-8 and Latin-1 encodings are auto-detected.
Yes. Export as an HTML diff report (preserving color highlights), or export added/removed/modified rows individually as CSV files. Great for archiving and sharing comparison results.
