JSON Master
Read full descriptionHide full description
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. LEGAL • Privacy Policy: https://vybgss.github.io/json-master-docs/privacy-policy.html • Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is in-app purchases: JSON Master at none against RenPyLinter's 4. RenPyLinter's advantage is update cadence (fortnightly vs every 2 months). On price, ads, device support and iOS requirement there is nothing between them.
