JSON Master
Outils de développement
Gratuit
JSON Master is a native JSON editor built around what you actually do with JSON every day: find the value, copy its path, understand what a field really contains — and fix the file when it doesn't parse.
See the whole document as a tree and as colour-highlighted source, side by side on iPad and Mac. Both are the same file: change one, and the other follows.
FIND YOUR WAY
• Command palette: type a few letters and jump to any node or run any command — "custcity" finds customer.address.city
• Breadcrumbs, back and forward after every jump
• Search keys and values, step through matches
• Full keyboard navigation on Mac and iPad
UNDERSTAND A VALUE
• Unix timestamps shown as readable dates
• JWT tokens decoded: header, claims and expiry
• base64, ISO dates and URLs recognised on sight
• Warnings for integers too large for JavaScript
• Collapsed branches show their first keys, so you often don't need to open them
QUERY, COMPARE, GENERATE
• JSONPath queries with live results — tap one to jump to it
• Compare two documents by structure, not by line breaks
• Generate Swift Codable, TypeScript interfaces or JSON Schema
• Summary with node counts, depth and findings worth a look
FIX AND EDIT
• A broken file shows the exact line and column of the error
• One-tap repair for almost-JSON: comments, trailing commas, single quotes, bare keys
• Edit keys and values, change types, add, duplicate and delete — every edit undoable
• Format, minify, sort keys, expand embedded JSON strings, convert JSON Lines
• Copy paths in six notations: dot, JSONPath, brackets, jq, Swift and JSON Pointer
MADE FOR LARGE FILES
Files of tens of megabytes open without freezing, with progress shown while they load.
YOUR WAY
Four themes — Midnight, Graphite, Amber CRT and Daylight — and seven languages: English, German, French, Ukrainian, Spanish, Japanese and Portuguese.
No account, no ads, no tracking. Your files stay on your device.
