What does JSON Diff do?

JSON Diff compares two JSON objects and shows the differences between them. It identifies added keys, removed keys, and changed values at any nesting level, making it easy to see what changed between two versions of JSON data.

What is it used for?

  • API Development: Compare API request/response payloads
  • Configuration Changes: Track changes in JSON config files
  • Debugging: Identify unexpected data changes
  • Code Review: Review JSON schema or fixture changes
  • Data Migration: Verify data transformation accuracy

Difference Types

  • Added (+): Keys that exist in modified JSON but not in original
  • Removed (-): Keys that exist in original JSON but not in modified
  • Changed (~): Keys that exist in both but have different values

How it works

Paste the original JSON in the left field and the modified JSON in the right field, then click Compare. The tool recursively compares both objects and shows all differences with their full paths. Nested objects and arrays are compared deeply. All processing happens in your browser.
