Paste messy JSON and get clean, readable, correctly indented output in one tap. JSONViewer formats, validates, and beautifies any payload — right on your iPhone, fully offline. Most JSON tools are websites that make you paste sensitive API data into a stranger's server. JSONViewer keeps everything on your device: paste a response, a config file, or a log export, and it pretty-prints with color syntax highlighting instantly. Invalid JSON is flagged with the exact reason so you fix broken payloads fast — no guessing, no round trips to a browser. WHAT YOU GET - Clean, indented JSON from any pasted or copied payload in one tap - Instant validation that pinpoints exactly why a payload is broken - Minify mode to strip whitespace down to a compact one-liner - An interactive, collapsible tree so you can read deeply nested data at a glance - JSONPath queries that pull the exact value out of a large response - A saved library of your own snippets plus ready-to-use sample payloads PERFECT FOR - Backend and mobile developers debugging API responses on the go - QA engineers checking payloads and config files away from a laptop - Students learning JSON structure with the built-in Learn guide - Anyone who needs to read or clean a JSON blob without opening a website WHY NOT JUST USE A WEB FORMATTER? Online formatters send your JSON to a remote server — a real problem when the payload holds tokens, user records, or internal data. JSONViewer does all parsing on-device, so your data never leaves your phone and works with no signal at all. PRIVACY Your JSON never leaves the device. No accounts, no servers, no tracking — everything runs locally, even in airplane mode. FULL ACCESS The Format tab — paste, validate, beautify, minify, and copy — is free. Premium unlocks the interactive tree view, JSONPath query, saved snippet library, and expand/collapse controls.
