What is a text diff checker?
A text diff checker compares two versions of text and identifies where they differ. It can help you spot lines that were added, removed, or changed without manually reading both versions from beginning to end.

Tips for accurate text comparison
Compare versions that use similar formatting when possible. Changes in line breaks, spacing, or formatting can appear as differences even when the underlying wording is similar. For structured files such as JSON or source code, formatting both versions consistently can make the results easier to review.
