A CSV viewer opens, filters, sorts, and exports CSV files entirely in your browser — no upload, no signup.

Private by default

Your file is parsed locally with papaparse and never leaves the page. Filter across all columns, sort any column (numeric-aware), and export the result to clean CSV or JSON.

Frequently asked questions

Is my file uploaded?

No. The CSV is parsed in your browser with papaparse and never leaves your device — ideal for sensitive exports, customer lists, or financial data. Verify in DevTools → Network: nothing carries your file.

How big a file can it handle?

Parsing handles large files fine; the on-screen table renders the first 500 filtered rows for speed, but export (CSV/JSON) always includes every filtered row. For multi-hundred-MB files a database tool is better.

Can I sort and filter?

Yes. Type in the filter box to keep rows matching across any column; click a column header to sort (numeric columns sort numerically, others alphabetically; click again to reverse).

What can I export to?

CSV (re-serialized cleanly) or JSON (an array of objects keyed by header). Both reflect the current filter.
