JSON Tools for Developers
JSONFORGE // DEVELOPER WORKSTATIONJSONForge is a collection of fast developer tools for working with JSON and related data formats. Convert JSON to TypeScript interfaces and types, Zod schemas, JSON Schema, CSV, YAML, and XML securely and deterministically in your browser.
Convert JSON to TypeScript interfaces and types instantly with recursive type inference.
Convert raw JSON payloads into clean, strongly-typed TypeScript interfaces and type definitions
Generate runtime Zod schema validation rules and inferred static types from sample JSON payloads
Generate standard IETF Draft-07 and 2020-12 JSON Schema contracts from sample data
Generate synthetic, realistic test datasets from custom templates or inferred structures
Prettify, indent, minify, sort keys alphabetically, and validate syntax with zero latency
Automatically fix invalid, broken, and malformed JSON, JS object literals, and AI outputs
Validate JSON syntax and structure against RFC 8259 specifications with exact line error markers
Compare two JSON objects or files side-by-side with visual addition, deletion, and edit highlights
Interactive hierarchical tree explorer with instant dot-notation and JSONPath expression copying
Test and extract data using JSONPath filter expressions, slices, conditions, and recursive search
Reshape, pick, omit, rename keys, flatten hierarchies, and change naming casing without writing scripts
Render JSON arrays as interactive sortable, searchable, and paginated data tables
Convert JSON arrays into RFC 4180 compliant CSV, TSV, or custom-delimited spreadsheet files
Bi-directional conversions between JSON, YAML, and XML with fine-grained mapping controls
Convert JSON into compact TOON format for token-efficient AI and structured data workflows
Convert compact TOON data back into standard JSON for applications and APIs
