How to use the online csv viewer and editor

  1. Open a CSV, TSV or Excel file — the delimiter is detected automatically.
  2. Search across all columns, click a header to sort, or click any cell to edit it.
  3. Download the result as CSV or as an Excel workbook.

A quick way to look inside large CSV exports without installing anything: product feeds, bank statements, contact lists or log files. The table view keeps the header row fixed while you scroll, sorts numbers numerically and text alphabetically, and lets you fix typos directly in the cells. Up to 2,000 matching rows are shown at once; search narrows the view. Your data stays on your device.
