What Text Diff does

Use Text Diff when you need to compare revised copy against an original draft.

When to use it

  • Compare revised copy against an original draft.
  • Spot changed lines in small config or CSV snippets.
  • Review edits while ignoring whitespace or case when those differences are noise.

How to use it

  1. Paste the original text on the left and the changed text on the right.
  2. Set ignore options if whitespace or case should not count.
  3. Review added, removed, and changed lines before accepting edits.

What to check

  • Line-based diff can miss subtle word changes inside very long lines.
  • For source code, use your version control diff before committing.

Data, formats, and limits

What stays on your device and what is sent

Runs in your browser. Input, settings, and results are not sent to Utilio servers.

Supported formats

This tool works with typed or generated values rather than uploaded files.

File limits and browser requirements

  • Use an up-to-date browser and check the result on the device where you will use it.

Known limits

  • Text processing depends on characters, line breaks, and Unicode details in the source text.
  • Before publishing or sending the result, check it in the app where it will be used.

Troubleshooting

  • If the result is unexpected, check line breaks, extra spaces, and hidden Unicode characters.
  • If pasted text from a phone or document looks odd, paste it into a plain text editor first and copy it from there.
  • Before publishing, check the result where the text will actually be used.
