What is a JSON Diff?

A **JSON Diff** (or JSON Compare) is a process used by developers to identify structural differences between two JSON objects. Unlike a simple text comparison, a semantic JSON diff understands the data hierarchy, ignoring irrelevant differences like whitespace or the order of keys, and highlighting only the actual data changes (additions, deletions, or value updates).

How to Compare JSON Files

  1. 1

    Input Version A

    Paste your original JSON code into the left panel. This serves as the "Baseline" for the comparison.

  2. 2

    Input Version B

    Paste the modified JSON code into the right panel. The tool will immediately validate both inputs.

  3. 3

    Analyze Differences

    Click 'Compare'. The tool will generate a list of changes. Green indicates additions, Red indicates removals, and Yellow indicates modifications.

Why use this Diff Tool?

Semantic Logic

Don't waste time on false alarms. We ignore key reordering and insignificant whitespace changes, focusing only on what matters.

Deep & Nested

Whether it's a flat object or a deeply nested API response, our recursive algorithm tracks changes down to the exact node path (e.g., `data.users[0].id`).

Instant Feedback

Get a clear, visual summary of all changes. Copy the change log to your clipboard to document API updates or configuration drifts.
