Our verdict on JSONLint

JSONLint is a browser-based toolkit for developers who work with JSON across validation, transformation and code-generation tasks. The free Web Tools plan brings more than 40 tools for JSON validation, formatting, beautification, minification, JSON Schema validation and generation, JSONPath querying, document comparison, format conversion and code generation. It supports conversions between JSON and CSV, XML, YAML, Excel and SQL, and can generate code for languages including TypeScript, Python, Java and Go. The web tools run in the browser, while JSONLint Pro is a separate native macOS editor.

Pricing is straightforward. Web Tools are free and cover the browser-based toolkit. JSONLint Pro costs $6.99 as a one-time purchase and adds a native macOS editing environment with offline support, real-time validation, smart repair and format conversions. The paid tier is therefore aimed at developers who want a local editor rather than only browser utilities. Buyers who need browser access across their workflow can start with the free plan, while macOS users working with local files may find the one-time Pro purchase more relevant.

The main strength is breadth: JSONLint combines syntax error reporting, schema work, JSONPath filtering, diffing, conversion and programming-language code generation in one product. That makes it a practical fit for varied development workflows instead of a tool limited to formatting or validation. The trade-off is platform separation. The browser tools and the native editor are distinct offerings, and the native experience is tied to macOS. Choose JSONLint for broad JSON conversion and code-generation work, especially if free browser tools meet your needs or you want a low-cost macOS editor. Choose another option if you require a native editor outside macOS or only need a narrowly focused JSON utility.

How long have you used it?

I've used JSONLint myself and this is my honest opinion — nobody paid or asked me to write it.
