JSON tools

Format, diff, tree-view, schema, JSONPath, types and CSV↔JSON helpers that run in your browser on LocalKit.

• JSON Formatter — Beautify, minify and validate JSON in your browser with LocalKit. Catch syntax errors locally—no upload, no account, ideal for API payloads and config drafts.
• JSON Tree Viewer — Browse JSON as an expandable tree locally in LocalKit. Inspect nested API payloads without uploading them.
• JSON Diff — Compare two JSON documents and highlight structural differences in LocalKit. Review API payloads locally—documents stay in your browser with nothing uploaded.
• JSONPath Tester — Evaluate JSONPath queries against JSON in your browser with LocalKit. Probe payloads locally—documents stay on-device with nothing uploaded for computation.
• JSON Schema Tool — Validate JSON against a schema or generate a draft schema from samples in LocalKit. Check contracts locally—documents stay on-device with nothing uploaded.
• JSON to Types — Generate TypeScript, Go, Python or other type definitions from JSON in LocalKit. Scaffold models in your browser—samples are not uploaded for computation.
• CSV ↔ JSON — Convert CSV tables to JSON objects and back locally in LocalKit. Prep sample data in your browser—spreadsheet content is not uploaded for computation.

All listed tools run in your browser. LocalKit does not upload content for computation.
