JSON Comparator

Compare two JSON documents and find differences. See what's been added, removed, or modified between versions.

Deep JSON Comparison Tool

Our JSON comparator performs deep comparison of two JSON documents, identifying every difference at any nesting level. This is essential for debugging API changes, tracking configuration modifications, and version control.

What Gets Compared

  • Added properties: New keys that exist only in JSON 2
  • Removed properties: Keys that were in JSON 1 but not JSON 2
  • Modified values: Properties that exist in both but have different values
  • Nested objects: Deep comparison of nested structures
  • Arrays: Full comparison of array elements

Use Cases

  • API development: Compare API response versions
  • Config management: Track configuration changes
  • Database auditing: Compare document snapshots
  • Testing: Verify expected vs actual output
  • Debugging: Find what changed between working and broken states

Understanding Results

Each difference shows the full path to the changed value using dot notation (e.g., user.address.city). This makes it easy to locate exactly where changes occurred, even in deeply nested structures.

Tips for Effective Comparison

Format both JSON documents before comparing for cleaner results. For large documents, focus on the summary counts first. Use this tool alongside our JSON formatter for a complete JSON workflow.
