#About JSON Diff
Free online JSON diff tool. Compare two JSON objects and see added, removed, and modified keys with a structure-aware visual diff. This tool runs entirely in your browser — your data is never sent to a server. Just paste your input, get instant results, and copy with one click. No sign-up or installation required.
#FAQ
How is JSON diff different from text diff? ▾
Text diff compares line by line, which can produce misleading results when keys are reordered. JSON diff compares the actual structure and values, so reordering keys does not show as a change.
What types of changes are detected? ▾
The tool detects added keys (present only in the second JSON), removed keys (present only in the first), modified values (same key, different value), and type changes (e.g., string to number).
