What is JSON to Elm?
JSON to Elm is a focused developer workspace that helps you generate Elm types and decoders from JSON. It uses established parsers and compilers instead of brittle regular-expression transformations. Normal input remains in the browser, and the page shares RankSmartTools navigation, theme, access controls, search, metadata and download behavior.
Generate Elm types and decoders from JSON. This makes it useful for API responses, configuration files, test fixtures and data exchanged between development systems.
How to use JSON to Elm
- Paste source text or load a compatible local file.
- Choose the primary action and review any parser diagnostics.
- Inspect, copy or download the generated output.
- Clear sensitive content when finished; browser memory is opt-in.

}Frequently asked questions
No. Formatting and conversion parse text but do not run submitted scripts or commands.
Normal operations run locally in the browser. Remote URL loading is clearly identified as a server operation where available.
Equivalent data structures are preserved where the formats overlap. The output and page notes identify transformations that cannot represent format-specific features exactly.
