How to Use This Tool

This tool renames the headers of your CSV columns. Select which columns to rename, type the new name for each, and the output updates instantly. Data values are unchanged.

  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. Select columns to rename — Use the dropdown to add columns. Type the new name in the text input next to each.
  3. Get your output — Copy the result to your clipboard or save it as a .csv file.

FAQ

3 questions
Does this tool upload my data?
No. It runs entirely in your browser using JavaScript. Your CSV data is never sent to a server.
Does it change the data in the columns?
No. Only the header names are changed. All cell values remain exactly the same.
What happens to columns I don't rename?
They keep their original headers. Only the columns you explicitly add to the rename list are affected.
