How to Use This Tool

Minify your CSV file by trimming whitespace from all cells, removing empty rows, and outputting the most compact representation possible. This reduces file size without losing any actual data values.

  1. Provide your CSV — Paste CSV text into the input area, drop a CSV file onto the File tab, or enter a URL on the URL tab.
  2. Review the output — Your CSV has been compressed with all unnecessary whitespace and empty rows removed.
  3. Get your output — Copy the minified CSV to your clipboard or save it as a .csv file.
