About JSON Parser

Our Story

JSON Parser started with a problem every developer knows. You get a big API response back, and reading it as raw text is slow and painful. A lot of online tools were cluttered, asked you to sign up, or fell over on deeply nested data. So we built one that does the simple thing well: paste JSON, get a readable table.

The first version did exactly that and nothing else. Since then we've added formatters, validators, fixers, converters and code generators for JSON, XML, YAML, CSV, Protobuf, Avro and more, all built on the same simple layout.

The goal hasn't changed: free tools that load fast, need no account, and get out of your way so you can get back to work.

What We Offer

JSON Parser is a collection of free online tools for working with JSON, XML, YAML, CSV, and other data formats. Parse, validate, format, convert, and fix your data – most tools run directly in your browser with no server uploads.

Most tools process everything locally on your computer, which means your data stays private and you get instant results. The AI-powered fixers and code-to-JSON converters are the exception: they send your input to our server so the AI model can process it, and we don't store it. Our tools follow official specifications for JSON, ensuring standards-compliant output.

Our Mission

We believe great tools should be accessible to everyone. Whether you're a senior engineer at a Fortune 500 company or a student learning to code, you deserve access to professional-grade tools without barriers.

That's why we keep JSON Parser free and focused. The site is paid for by ads, which lets us keep building new tools without charging for them.
