A diff highlights changes between two versions of text. It is useful for drafts, configuration, and code review, but line-based comparisons can look noisy after large formatting or line-ending changes.
Make a diff easy to review
Use clearly labeled original and revised text. If unrelated formatting changed, normalize it first so the comparison focuses on meaningful edits.
- Paste the earlier version in the first pane.
- Paste the newer version in the second pane.
- Review additions and removals in context.
- Confirm that every important change is intentional.
Keep in mind: Diff results show textual changes, not whether the revised content is correct or safe to run.
