About this tool
Compares two blocks of text or JSON side by side or inline, with options to ignore whitespace or case differences.
When you’d use it
- Reviewing what changed between two versions of a config file before a code review.
- Comparing two JSON payloads to spot a field that quietly changed.
Frequently asked questions
- Does JSON mode compare values or just raw text?
- JSON mode parses both sides and diffs the structured result, so key reordering that doesn't change meaning won't get flagged as a difference the way a plain text diff would.
