Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Format, validate, convert, and diff JSON on iPhone and iPad. Tree and table views, JSONPath, schema tools, and local-only processing—no account required.
JSON DevKit is a JSON workbench for iPhone and iPad. View, edit, format, validate, convert, and compare JSON in one place—built for developers, QA engineers, and API testers who need fast answers on mobile.
CORE WORKFLOW
• Open JSON from the editor, clipboard, files, or a URL
• Pretty-print or minify with syntax highlighting and line numbers
• Explore structure in tree view or flatten nested data into a table
• Run JSONPath queries and inspect matched results
• Generate and validate JSON Schema
• Compare two JSON documents with a synced side-by-side diff
• Convert JSON to CSV, TSV, XML, YAML, TOML, TOON, Markdown table, HTML, or Base64
• Generate model stubs for Swift, Kotlin, TypeScript, Dart, Java, Python, and C#
BUILT FOR REAL WORK
• Multi-tab workbench keeps source and output snapshots as you switch tools
• Large payloads are processed off the main thread with progress feedback
• iPhone and iPad layouts adapt to your device—same tools, optimized navigation
• Recent history helps you return to earlier documents quickly
PRIVACY BY DESIGN
• All JSON processing happens on your device
• No account required to use core features
• Firebase Analytics (Google) collects anonymous usage events only—no JSON content or ad identifiers
• No ads and no subscription; optional one-time unlock for extended daily use
• Your data stays local unless you explicitly copy, share, or export it
Whether you are debugging an API response, checking a config file, or converting JSON for a report, JSON DevKit keeps the workflow focused and fast.
