JSON Master
Read full descriptionHide full description
JSON Master is a fast, native JSON editor for iPhone, iPad and Mac, built around what you do with JSON all day: find a value, copy its path, copy a branch, and understand what a field really contains. The document is shown two ways ā as a tree and as highlighted source ā and both are the same file. The tree is for reading and restructuring, the source for fixing what does not parse. FIND YOUR WAY ⢠Command palette (āK): every command by name and a fuzzy jump to any node ⢠Breadcrumbs, plus back and forward after every jump ⢠Search over keys and values; matching branches open by themselves ⢠Full keyboard control on Mac and iPad READ ⢠A tree with type badges, item counts, indent guides and previews of collapsed objects ⢠Highlighted source that keeps working even when the file does not parse ⢠A broken file explains itself: the exact line and column, one tap away ⢠One-tap repair for almost-JSON: comments, trailing commas, single quotes ⢠Large files open in the background without freezing COPY ⢠Paths in six notations: dot, JSONPath, brackets, jq, Swift and JSON Pointer ⢠Values, whole branches (formatted or minified), keys and key-value pairs UNDERSTAND The inspector recognises Unix timestamps, JWT tokens, base64, ISO 8601 dates, URLs and integers too large for JavaScript ā and shows what they mean. TOOLS ⢠Format, minify, sort keys, unwrap JSON embedded in strings ⢠Export as JSON or minified JSON JSON MASTER PRO One in-app purchase, no subscription, for iPhone, iPad and Mac: ⢠JSONPath queries with results as you type ⢠Structural compare: reordered keys and reindentation are not differences ⢠Generate Swift Codable, TypeScript interfaces or JSON Schema ⢠A summary that flags duplicate keys, unsafe integers and JSON hidden in strings ⢠Export as CSV ⢠Graphite and Amber CRT themes EVERYWHERE ⢠Tree and source side by side on Mac and iPad ⢠Midnight and Daylight themes, plus Graphite and Amber CRT with Pro ⢠Seven languages: English, German, French, Ukrainian, Spanish, Japanese and Portuguese. The app follows your system language or the one you choose for it No account, no ads, no tracking.

Verdict
The clearest difference is in-app purchases: Monkeytail at none against JSON Master's 1. Monkeytail also leads on update cadence (every 4 days vs every 8 days) and device support (5 vs 3). On price, ads and iOS requirement there is nothing between them.
