Converters
Convert between data formats and generate code from JSON.
One place for format and code conversion
Converters bridge formats and languages. When an API returns JSON but your system expects XML, or your config is in YAML and you need JSON, the format converters handle it. When you have a JSON sample and need type definitions or classes in TypeScript, Python, Java, Go, C#, Dart, Rust, Kotlin, Swift, or PHP, the JSON-to-code converters generate them from your structure. This hub collects all of these in one place so you can move between formats and code without leaving the platform.
Every converter runs in your browser. Paste input, get output. No uploads, no accounts, and no rate limits. The same editor and shortcuts you use for formatters and validators apply here.
Format conversion vs code generation
Format converters (JSON to XML, JSON to CSV, JSON to YAML, XML to JSON, YAML to JSON, CSV to JSON) transform data from one serialization to another. Use them for integration, migration, or when downstream tools expect a different format. Code converters (JSON to TypeScript, Python, Java, etc.) take a JSON object and produce class or type definitions in the target language—useful for generating DTOs, API client types, or documentation from real payloads. Both kinds are available from this hub and from the relevant category hubs (e.g. JSON tools, XML tools) so you can start from either the format or the converter view.

Frequently Asked Questions
What can I convert?
You can convert JSON to XML, CSV, YAML, and to code in multiple languages (e.g. TypeScript, Python, Java, Go). We also provide XML to JSON and YAML to JSON, plus CSV to JSON.
Are converters safe for sensitive data?
Yes. All conversion runs in your browser. No data is sent to our servers or any third party.
Do I need an account?
No. Every converter is free to use without registration.
What languages can I generate from JSON?
We offer JSON to TypeScript, Python, Java, Go, C#, Dart, Rust, Kotlin, Swift, and PHP—generating class or struct definitions from your JSON structure.
Where do I find JSON to CSV?
JSON to CSV is available as a dedicated tool and from the convert bar on JSON formatter/validator. Use it to turn JSON arrays into spreadsheet-friendly CSV.
