Haskell to Crystal Converter

developer100% Client-Side

Convert Haskell code to Crystal online — free, instant, and 100% private in your browser.

Passthrough onlyNo rewrite rules exist for this pair yet — your code is returned annotated, not translated. Try routing through Python or JavaScript.
  • No dedicated Haskell → Crystal rules yet. Output is annotated source for manual editing.

Rewrite rules cover 13 source and 13 target languages (Python, JavaScript, TypeScript, Java, C#, Go, Ruby, PHP, Rust, Kotlin, Swift); the remaining 31 are listed for reference and pass through annotated rather than translated. Complex projects still need manual review — all processing runs locally in your browser.

About Haskell to Crystal Converter

Haskell to Crystal Code Converter

Port algorithms, interview snippets, and learning examples from Haskell to Crystal without installing compilers or online APIs. ToolSphere runs conversion logic locally so proprietary or assignment code stays private.

Typical use cases: migrating utility scripts, comparing syntax across languages, preparing Crystal stubs from Haskell prototypes, and speeding up CS homework refactoring.

Select your languages, paste code, and iterate with swap-and-edit until the output matches your target idioms.

Haskell to Crystal has no rewrite rules yet. The converter has no Haskell-to-Crystal rules, so this page returns your source annotated rather than translated. It is kept for reference — for a working conversion, route through Python or JavaScript, which are the languages the engine understands best.

Frequently Asked Questions

Can this tool convert Haskell to Crystal automatically?

Not yet. Rules exist for Python, JavaScript, TypeScript, Java, C, C++, C#, Go, Ruby, PHP, Rust, Kotlin and Swift. For anything else the output is your original code with a header comment, and converting by hand through one of those languages is the practical route.

Is my source code uploaded to a server?

No. Conversion runs entirely in your browser with JavaScript. Your code never leaves your device.

How accurate is automatic code conversion?

Popular pairs (Python, JavaScript, Java, Go, C#, etc.) use dedicated rewrite rules. Other pairs may use a JavaScript pivot or annotated passthrough — always review before production use.

Can I convert entire projects?

This tool is optimized for snippets, homework samples, and algorithm ports. Multi-file projects need manual structure and import adjustments.

Does this support every Haskell library?

No. Standard language syntax is mapped; framework-specific APIs must be rewritten manually in Crystal.
