About JSON Utility

JSON Utility is a free collection of browser-based tools for working with JSON, YAML, and XML: a validator, formatter, converter, JSON Schema validator, JSONPath evaluator, and diff tools for JSON, YAML, and XML. Every tool runs entirely client-side — nothing you paste or upload is sent to a server.

These are the everyday tools a developer reaches for when debugging an API response, comparing config files, or checking a payload against a schema. JSON Utility was built to make that fast, free, and ad-clutter-light, without requiring an account or uploading data anywhere.

JSON Utility is built and maintained by an independent developer. It's a small, focused project — no company, no team, just tools kept simple and working.
