What is Encoding Fixer?

Detects common encoding issues (mojibake, replacement characters, BOM problems) in CSV files and provides fixes.

How it works

Scans the text for common mojibake patterns (e.g., é instead of é), replacement characters (�), and BOM presence. Provides BOM add/remove options.

  1. Paste CSV with issues. Paste CSV text that has garbled characters or encoding problems.
  2. Review detected issues. The tool lists all detected encoding problems.
  3. Apply fixes. Toggle BOM add/remove options as needed. Copy the fixed output.

Frequently asked questions
