When local comparison matters
- Comparing SQL query revisions before a deployment or review
- Checking how formatted HTML differs from the original snippet
- Reviewing config changes that include internal hostnames or tokens
Simple workflow
- Prepare the original version and the revised version.
- Paste both into the diff checker.
- Review removed lines, added lines, and whether the cleaned version introduced unexpected changes.
