Working with Text Diff

A text diff is useful for reviewing configuration edits, code snippets, or generated output. Read the highlighted lines in context and use the whitespace setting deliberately. Export the result when you need to keep a record of a comparison.

How to use Text Diff

  1. Paste the original text and the changed text into their respective editors.
  2. Adjust whitespace or case comparison options as needed.
  3. Review highlighted additions and deletions, then copy or export the comparison.

Text Diff example

Compare two small configuration files where one setting changed and a new line was added. Check both the deleted and inserted lines rather than relying only on a change count.

What to expect from the result

The diff is text-based, not a parser for a particular programming language. Reordered lines may appear as removals and additions even when an application's behavior is unchanged.
