14 tools, one page
Everything JSON Studio does, in one place. Start typing to filter — or press ⌘K from any page on the site to jump straight to a tool.
Inspect & debug
Read, clean and interrogate a payload you were just handed.
Formatter & validator
Beautify, minify, sort and escape JSON, with parse errors pinned to the exact line and column.
JSON to diagram
Turn any payload into a collapsible, searchable node graph. Export as PNG or SVG.
JSON diff
Compare two payloads structurally — key order ignored — and export an RFC 6902 JSON Patch.
JSONPath tester
Write a path and watch matches update live. Filters, slices and recursive descent.
JWT decoder
Read a token’s header, claims and expiry, and verify HS256 signatures locally.
Schema & test data
Describe the shape of your data, then check and fake it.
JSON Schema generator
Infer a schema straight from a sample payload — draft 2020-12 or draft-07.
JSON Schema validator
Check a payload against a schema and get every failure with its instance path.
Mock data generator
Turn a schema into realistic fake records. Seeded, so the same seed gives the same data.
Convert & export
Move a payload into whatever format the next system speaks.
JSON to code
Generate C# classes, TypeScript interfaces, Dart, Kotlin, Java, Python or Go types.
JSON ⇄ CSV
Convert to spreadsheet-ready CSV and back, with nested objects flattened to dot columns.
YAML ⇄ JSON
Convert either direction with live validation and multi-document YAML support.
JSON ⇄ XML
Convert either direction with attributes preserved, using the browser’s own parser.
JSONL ⇄ JSON
Convert NDJSON logs and LLM datasets to an array and back, with bad lines flagged.
JSON to SQL
Generate CREATE TABLE and INSERT statements for Postgres, MySQL, SQL Server or SQLite.
