## What is 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.

• Recent Files: A new jump-list sheet remembers the last files you opened. Tap to reopen, even files stored outside the app on iOS.

• Native iOS Document Picker: All-new native file open/save experience with proper security-scoped bookmarks, so files from iCloud Drive, the Files app, and external providers just work.

• Remembers Your Last Conversion: The format you used last time is selected automatically the next time you launch.

• Redesigned Action Toolbars: Grouped floating action clusters on every screen for cleaner reachability and a more focused workspace.

• Organized Conversion Options: Conversion targets are now grouped into Visualizers, Transformers, Converters, and Generators, so the right option is always one tap away.

• Sharper Code Editor: JetBrains Mono for code, refined line numbers, a streamlined keyboard toolbar, and a cleaner syntax highlighter across all formats.

• Polished iOS Theme: Refreshed light and dark themes with better contrast, smoother surfaces, and tighter visual rhythm.

• New Settings Screen: Centralized control over theme, auto-copy, conversion memory, line numbers, word wrap, and editor toolbar visibility.

• Performance: Schema validation runs off the main thread, so larger files validate without freezing the UI.
