JSON Diff Guide

Use JSON Diff to compare two payloads side by side with inline highlighting and a quick summary of differences.

Quick steps

  1. Paste JSON A on the left and JSON B on the right.
  2. Format or normalize if needed.
  3. Review inline differences and the summary badges.

Best uses

  • Compare API responses across releases.
  • Validate config changes before deploys.
  • Find missing keys or unexpected values fast.

Common issues

  • Invalid JSON on either side blocks comparison.
  • Large payloads can slow diff rendering.
  • Key order differences may appear if not normalized.
