The most powerful JSON tool for iPhone and iPad — view, edit, format, validate, compare, and convert JSON files with a beautiful, intuitive interface. TREE VIEW & CODE VIEW View JSON in an interactive tree with expand/collapse, search, and breadcrumb navigation. Switch to formatted code view with syntax highlighting and line numbers. Sort keys alphabetically with one tap. FULL JSON EDITOR Edit JSON with a smart editor featuring line numbers, live validation, and a keyboard shortcuts bar. Add, edit, delete, duplicate, and clone nodes directly in the tree view. The built-in JSON Fixer automatically repairs broken JSON — missing quotes, trailing commas, unquoted keys, and more. EXPORT & CONVERT Export JSON as PDF documents or Excel spreadsheets. Copy as YAML, CSV, Key=Value pairs, or XML. Save to Files or share via any app. Print directly from the app. API CLIENT Send HTTP requests (GET, POST, PUT, DELETE, PATCH) with custom headers and body. View responses with status codes, timing, and size. Open any API response directly in the JSON viewer. Save request history for quick access. JSON COMPARE Load two JSON files side by side and see every difference color-coded — additions in green, deletions in red, changes in yellow. Paste, open from files, or fetch from URLs. VALIDATE & QUERY Validate JSON against any schema (JSON Schema Draft 7). Use JSONPath expressions to extract specific data with live results. Get detailed error messages with exact line and column numbers.
