About this tool
Whether you're comparing two config files, two versions of a paragraph, or API responses before and after a change, a visual diff makes it far faster to spot what actually changed than reading both versions side by side.
How it works
- Paste the original text on the left and the changed version on the right.
- Choose to compare by line (good for code/config) or by word (good for prose).
- Additions are highlighted green, removals are highlighted red and struck through.
Frequently asked questions
Can I diff JSON or YAML files?
Yes — paste the raw text of each file. For structural comparison rather than plain text, format both with the JSON Formatter first so whitespace differences don't show up as noise.
