CSV Helper한국어

CSV Checker

When a CSV saved from Excel breaks or shifts in another program, this tells you which line is wrong.

🔒 Files are processed only inside your browser and are never sent to a server.

How to use

  1. Choose or drop a CSV file.
  2. Encoding and delimiter are detected automatically. If text looks broken, choose the encoding yourself.
  3. Fix the lines listed in the results. Problem rows are highlighted in the preview.
