Comparing JSON Objects
When an API response changes or a config file gets updated, spotting the differences manually is painful.
This tool compares two JSON objects and highlights exactly what was added, removed, or changed — much like
a git diff but specifically for structured data.
Unlike plain text diff, JSON diff understands structure. It knows that {"a":1,"b":2} and
{"b":2,"a":1} are equivalent, and it won't flag reordered keys as changes.
Common Use Cases
- API versioning — Compare responses between API versions to spot breaking changes
- Config auditing — See what changed between two versions of a config file
- Data debugging — When your app produces unexpected output, compare against expected data
Need to format a single JSON file first? Use the JSON Formatter. For comparing plain text or code, try the Diff Checker.
