JSON Viewer
View JSON in a clean readable layout with formatting, validation, folding, and Arabic-friendly character rendering for APIs, configs, and exports.
What JSON Compare Tool helps you do
This JSON diff and compare tool checks two JSON documents structurally and highlights which paths were added, removed, changed, or mismatched by type.
It is useful when comparing API responses, fixtures, deployment configs, and generated output where property order alone should not count as a meaningful change.
The page keeps the scope tight around comparison and debugging, while related tools handle formatting, token-aware conversion, and other dedicated JSON workflows.

Frequently asked questions
What does this JSON compare tool check?
It parses both inputs as JSON and compares the structure and values path by path.
Does property order matter?
Object property order does not matter when the values are otherwise the same, but array order still matters because arrays are positional.
Can it compare nested arrays and objects?
Yes. Nested objects and arrays are compared recursively.
What happens if one side is invalid JSON?
The tool returns a friendly validation error instead of attempting a partial diff.
Is this useful for API regression checks?
Yes. It helps spot response changes quickly during testing and debugging.
