All parsing happens locally using PapaParse in your browser. Your CSV is never uploaded.
FAQ
- What file size can it handle?
- Browsers can comfortably render 50,000+ rows, but the preview is virtualized at 200 rows for performance. Stats still run over the whole file.
- Which delimiter is supported?
- Comma, semicolon, tab, and pipe are auto-detected. You can override the choice in the controls.
- Can I sort or filter inside the preview?
- Yes — click column headers to sort. Use the CSV Sorter and CSV Filter tools for multi-key sort and regex filtering.
