JSON Toolkit is a clean, local-first Mac app for working with JSON without the usual friction
JSON Toolkit is a clean, local-first Mac app for working with JSON without the usual friction. Built for the real day-to-day annoyances of API and data work: broken payloads, escaped blobs, giant nested objects, quick before-and-after comparisons, and JSON you need to share without exposing the original values. Validate in real time as you type. Jump straight to errors. Beautify, minify, or unescape in a click. Explore valid documents in tree view, compare two payloads side by side, or anonymize sensitive data while preserving the overall structure. Features: • Real-time validation with inline errors and jump-to-error • Beautify, minify, and unescape tools • Tree view with expand/collapse and display controls • Side-by-side diff viewer in a dedicated workspace • Anonymize sensitive JSON with deterministic replacements • Multiple windows for comparing files without losing your place • Settings for theme, auto-beautify, tree behavior, and zoom Everything runs locally on your Mac. Parsing, diffing, and anonymizing stay on-device. No telemetry. No network calls. Made to feel fast, quiet, and dependable.
