All-in-one client-side JSON engineering workstation: multi-indent prettifier & minifier, real-time syntax error line detection, 1-click TypeScript interface & Zod schema generator, bidirectional YAML & CSV converter, and collapsible tree viewer with interactive JSONPath evaluator.

How It Works

  1. Paste your raw JSON into the input editor or load our sample payload.
  2. Format or minify with custom indentation, key sorting (A-Z), and Unicode escaping.
  3. Switch to the TypeScript & Zod tab to copy generated interfaces or Zod schemas.
  4. Switch to the YAML & CSV tab to convert data formats in one click.
  5. Explore nodes and extract JSONPaths using the Interactive Tree tab.

Frequently Asked Questions

How do I generate TypeScript interfaces from JSON?

Switch to the TypeScript & Zod tab. Our engine automatically analyzes nested structures, infers property types, marks missing keys as optional, and produces clean exportable interfaces.

Can this tool generate Zod validation schemas?

Yes! Select the Zod Validation Schema toggle to instantly generate importable z.object schemas and inferred TypeScript types (z.infer<typeof ...>).

How does the JSON to CSV and YAML converter work?

The YAML & CSV tab offers instantaneous client-side conversion. CSV conversion extracts tabular records and supports custom delimiters (comma, semicolon, tab).

What is the Interactive Tree & JSONPath feature?

It provides a collapsible visual explorer for complex nested JSON data. You can filter keys, expand/collapse nodes, and click any field to copy its exact JSONPath query string (e.g. $.data.team[0].name).

Is any JSON payload sent to an external server?

Zero data leaves your browser. All parsing, validation, TypeScript generation, and format conversions execute 100% locally in your browser memory.
