About

JSON Master is a JSON viewer and editor for the things you actually do all day: find the value, copy its path, copy the branch, and work out what a field really contains. Every document is shown two ways, as a tree and as coloured source, and both are the same file. WHAT MAKES IT DIFFERENT - Every path is ready to paste, in whichever form you need it: dot, JSONPath, brackets, jq, Swift or JSON Pointer - The inspector explains what a value really is: Unix timestamps as dates, JWT tokens decoded, base64, ISO dates, string length, integers beyond 2^53, duplicate keys - Expand embedded JSON, the escaped string every webhook and log line contains, unwrapped in place - Syntax colour that holds even when the document does not parse, which is exactly when it helps - An untouched file is saved byte for byte as it arrived, and a broken one still opens with the line and column of the error ALSO INSIDE Format and minify, sort keys, remove empty values and duplicate keys, JSON Lines to array, JSONPath queries, document summary, structural compare, type generation for Swift, TypeScript and JSON Schema, JWT decoding, export to CSV. Designed like an amber monitor: warm near-black surfaces, phosphor text, monospaced throughout. Seven interface languages, switching without a restart. No account, no tracking, no analytics, no network access. Your documents never leave your device. Universal app for iPhone, iPad and Mac.
