How to use the CSV Viewer & Formatter

  1. Paste CSV data or open a file.
  2. Click a column header to sort, or type to filter rows.
  3. Download the result with the delimiter you need.

What does this tool do?

Spreadsheet apps sometimes mangle CSV — dropping leading zeros or misreading dates. This viewer shows the raw values exactly as they are, with automatic delimiter detection and proper handling of quoted fields.

Rows with a different number of columns are flagged, which usually means a missing quote or delimiter. Everything runs in your browser; nothing you paste is uploaded.

Why use it?

  • Sort and filter instantly.
  • Flags broken rows.
  • Change the delimiter.
