JSON diff tool online

Inspect changed properties between two JSON payloads. Ignoring array order changes comparison semantics; repeated array values still matter.

How to use it

Enter Original JSON or select Try example. Provide Updated JSON in the second editor. Review Ignore array order. Select Run tool and inspect the result before copying or downloading.

Worked examples

Inspect changed properties between two JSON payloads.

Worked example — JSON Comparison

Settings: Ignore array order: Off

Input:

{"name":"Anna","active":true,"age":25}

SECOND INPUT:
{"age":26,"name":"Anna","city":"Tirana"}

Output:

[
  {
    "path": "/active",
    "change": "removed",
    "before": true
  },
  {
    "path": "/age",
    "change": "changed",
    "before": 25,
    "after": 26
  },
  {
    "path": "/city",
    "change": "added",
    "after": "Tirana"
  }
]

The example returns 3 top-level items in an array. Each item is a record; the first record contains “path”, “change”, “before”.

Choose the right tool

Whitespace and indentation do not count as value changes. Use Compare Text if the exact source lines matter; use this tool to compare parsed JSON structure.

Limitations and common mistakes

  • Ignoring array order changes comparison semantics; repeated array values still matter.
