🧮 JSON Diff
Compare two JSON structures and see a list of differences by path.
JSON Diff
Compare two JSON objects side by side. See differences in values, types, and missing keys. Perfect for debugging API responses or checking config changes.
b.cvalue mismatch⟵ 2⟶ 3
b.dtype mismatch⟵ ⟶ 4
How to use this tool
- Paste JSON objects into the left and right editors.
- Use Pretty Print if needed, then review the computed differences below.
- Copy the diff summary or reset to compare a new set of payloads.
Helpful scenarios
- Spot regressions in API responses between staging and production.
- Review infrastructure config changes before applying them.
- Compare exported settings files to understand what changed between versions.
Diff tips
- Keep JSON valid—invalid syntax results in a warning instead of a diff.
- Use meaningful keys to make the path column easier to read in team reviews.
- Pair with the JSON Formatter to clean up large payloads before diffing.
FAQ
- Does order matter?
- Object key order doesn't affect results, but array order does. Reordering array items will show as differences.
- Can I ignore specific paths?
- Not yet. For now, remove keys you want to ignore before running the diff.
- Is my JSON uploaded?
- No. Parsing and diffing happen entirely in your browser.
