JSON Tools

The ultimate JSON toolkit for developers. Visualize, validate, convert, and generate code - all in one powerful, beautifully designed iOS app.

JSON Tools is the professional-grade JSON utility built for developers who demand speed, precision, and versatility. Whether you're debugging API responses, prototyping data schemas, or generating type-safe model classes, JSON Tools handles it all natively on iPhone and iPad.

Visualize & Explore

Dive into your JSON with an interactive Tree View and JSONPath-powered querying. Use the Table View to inspect arrays like a spreadsheet. Rainbow column highlighting makes CSV/TSV output instantly readable.

Format & Transform

Prettify nested structures with smart indentation or strip whitespace with the Minify engine. Convert JSON to XML, CSV, TSV, TOML, YAML, HTML, Markdown, Base64, and more instantly.

Generate Production-Ready Stub Code

Export type-safe model classes for Dart, Swift, Kotlin, Java, Python, TypeScript, and C# with intelligent property singularization and pluralization. Stop writing boilerplate JSON Tools writes it for you.

Validate with Confidence

Auto-generate JSON Schema from any object, then validate payloads against it in real time. Catch errors before they reach production.

Built for iOS

A dedicated JSON syntax keyboard overlay, native Document Picker integration, and background processing keep the experience fast and fluid even on massive datasets.
