Why this tool stays in the browser

Diff two JSON objects locally when a fixture and a live payload disagree. Format each side in JSON Formatter first if the input is minified. This is not a git diff for arbitrary text — use Diff Viewer for that. YAML conversion is separate if one side is a config file.

FAQ

Are the two documents uploaded?

No. The comparison runs in the tab.

What if the JSON is invalid?

Format and validate each side in JSON Formatter, then return here.

Can I diff YAML?

Convert to JSON first with YAML ↔ JSON, then diff the JSON objects.
