JSON Viewer Pro is the fast, offline-first JSON toolkit for iPhone and iPad. Paste, import or type any JSON and instantly beautify it, minify it, validate it and explore it as an expandable tree. Built for developers, students, QA engineers and anyone who works with APIs, config files or data. BEAUTIFY AND MINIFY IN ONE TAP Turn a wall of compact JSON into clean, indented, color-coded text in a single tap. Switch between pretty print and minified output instantly. Choose 2-space, 4-space or compact indentation. Copy or share the result without ever leaving the app. VALIDATE WITH PRECISE ERRORS Catch malformed JSON the moment you paste it. The built-in parser reports exactly where the problem is โ character position, line and column โ so a missing comma or unclosed brace is never a mystery again. EXPLORE AS A TREE Collapse and expand any object or array to navigate deeply nested structures without scrolling through thousands of lines. Tap any node to copy its dot-path (users[0].name), perfect for building queries or referencing a value in your code. SEARCH KEYS AND VALUES Find every occurrence of a keyword across the whole document. Match keys, values or both. Toggle case sensitivity and whole-word matching. Each hit shows its full path, type and a preview, with one-tap copy. SYNTAX HIGHLIGHTING Keys, strings, numbers, booleans and null each get their own color, so the structure of your data is obvious at a glance. Output stays perfectly readable in both light and dark mode. SMARTER PASTING Pasted a Base64 or URL-encoded payload by accident? JSON Viewer Pro detects it and offers to decode it for you, so you can inspect the real JSON hiding inside. STATS AT A GLANCE See the total node count and maximum nesting depth of any document the moment it parses โ useful for sizing up an unfamiliar API response before you dig in. RECENT DOCUMENTS Every document you format or validate is saved to a local history list. Jump back to it with a tap, swipe to delete, or clear everything at once. WHY JSON VIEWER PRO One-tap beautify and minify with selectable indentation Precise validation with line, column and character position Expandable tree with copy-path for every node Full-text search across keys and values Color syntax highlighting for keys, strings, numbers, booleans and null Automatic Base64 and URL-encoded payload decoding Node count and depth statistics Local document history with swipe-to-delete Works fully offline โ your data never leaves the device No subscriptions, no ads, no sign-in.
