Three simple steps
How to use this tool?
This free online converter translates Haskell source code into Elm in three simple steps.
- Step 1
Add your Haskell code
Type, paste, or upload the Haskell code you want to translate.
- Step 2
Convert the code
Click Convert to translate the source code into Elm.
- Step 3
Review the result

Language comparison
Key differences between Haskell and Elm
| Characteristic | Haskell | Elm |
|---|---|---|
| Syntax | Haskell has a more complex and flexible syntax compared to Elm. | Elm has a simpler and more restricted syntax compared to Haskell. |
| Paradigm | Haskell supports multiple paradigms including functional, imperative, and declarative. | Elm is a purely functional programming language. |
| Typing | Haskell has a strong static type system with type inference. | Elm has a strong static type system with type inference. |
| Performance | Haskell is known for its high performance due to its lazy evaluation and compiler optimizations. | Elm is designed for front-end web development and focuses more on developer productivity than raw performance. |
| Libraries and frameworks | Haskell has a rich ecosystem of libraries and frameworks for various domains. | Elm has a smaller ecosystem of libraries and frameworks compared to Haskell, but it has a strong focus on front-end web development. |
| Community and support | Haskell has an active and supportive community with many online resources and forums. | Elm has a smaller but dedicated community with good support from the core team. |
| Learning curve | Haskell has a steep learning curve due to its advanced concepts and complex syntax. | Elm has a relatively gentle learning curve, especially for beginners, due to its simplicity and focus on front-end web development. |
Common questions
Frequently Asked Questions
How do I convert Haskell to Elm?
Paste your Haskell code into the input box, confirm the languages are set to Haskell and Elm, and click Convert. CodeConvert AI analyzes your Haskell code and generates equivalent Elm code in seconds, preserving the original logic and structure.
What are the main differences between Haskell and Elm?
Haskell and Elm differ in syntax, type system, standard libraries, and common idioms, so copying code line for line usually will not compile. The converter maps each Haskell construct to its closest Elm equivalent. See the comparison table below for the key differences between Haskell and Elm.
Is the converted Elm code accurate?
The AI produces high-quality Elm code that preserves the behavior of your original Haskell code and follows Elm conventions. It handles common patterns, data structures, and idioms for both Haskell and Elm. For large or performance-critical code, review and test the Elm output before using it in production.
Can I convert an entire Haskell project to Elm?
You can convert Haskell files one at a time by pasting each file's code. For a full migration, convert each file and then review how classes, dependencies, and project structure map from Haskell to Elm. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
Can I convert Elm back to Haskell?
Yes. CodeConvert AI converts in both directions, so you can convert Elm to Haskell just as easily using our Elm to Haskell converter. Try the Elm to Haskell Converter
Is the Haskell to Elm converter free, and do I need to install anything?
Yes, it is free and runs in your browser with nothing to install and no IDE extension required. You can convert Haskell to Elm without an account for up to 2 conversions per day. Sign in for free for higher limits.
What are the benefits of signing in?
Signing in unlocks CodeConvert AI's Pro converter with more powerful AI models, a built-in chat assistant, code execution, saved conversion history, and personal notes. Every free account includes 5 credits and supports up to 25,000 characters of input per conversion, with no credit card required.
