How to use
- Drop a CSV (or TSV) in — it opens as a spreadsheet-style grid with headers, row numbers and clean grid lines. The delimiter is detected automatically; switch it, or turn off “first row is header”, any time.
- Type in the search box to highlight every matching cell (with a match count), and tick “Only matching rows” to filter the table down. Click a column header to sort up, again for down, and a third time to restore the original order. Press ✕ on a header to hide that column — hidden columns sit in a chip bar so one tap brings them back.
- Press Export CSV to download exactly what you see: the visible columns, in the current sort order, filtered if a filter is on.
FAQ
Is my CSV uploaded anywhere?
No. The file is read, displayed, searched and exported entirely in your browser — it never leaves your device, so even confidential exports (customers, payroll, logs) stay private. The viewer works offline once the page has loaded.
Does it handle big or messy files?
Yes. The parser follows the real CSV rules — quoted fields, escaped quotes, commas and even line breaks inside cells — and auto-detects comma, semicolon or tab delimiters. Large files are shown in fast pages of 500 rows (up to 200,000 rows), and columns that look numeric are right-aligned and sort as numbers, not text.
What exactly does Export CSV save?
What you see. Hidden columns are left out, rows come out in the current sort order, and if “Only matching rows” is on, only those rows are saved. Quoting is handled properly, so cells containing commas or quotes survive the round trip — ready to open in Excel, Google Sheets or any other tool.
