Three simple steps
How to use this tool?
This free online converter translates Haskell source code into F# 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 F#.
- Step 3
Review the result
Review, copy, or download the resulting F# code from the output editor.

Language comparison
Key differences between Haskell and F#
| Characteristic | Haskell | F# |
|---|---|---|
| Syntax | Haskell has a more complex and mathematical syntax, with a strong focus on functional programming concepts. | F# has a simpler and more familiar syntax, influenced by C# and other mainstream languages. |
| Paradigm | Haskell is a purely functional programming language, emphasizing immutability and referential transparency. | F# is a multi-paradigm language, supporting functional, imperative, and object-oriented programming. |
| Typing | Haskell has a strong static type system with type inference, ensuring type safety and preventing many runtime errors. | F# has a strong static type system with type inference, similar to Haskell, ensuring type safety and preventing many runtime errors. |
| Performance | Haskell has a reputation for high performance due to its lazy evaluation and advanced compiler optimizations. | F# has good performance, comparable to other statically-typed languages like C# and Java. |
| Libraries and frameworks | Haskell has a smaller ecosystem of libraries and frameworks compared to more mainstream languages, but it has a strong focus on correctness and purity. | F# has access to the extensive .NET ecosystem, including libraries and frameworks for various domains. |
| Community and support | Haskell has a passionate and active community, with dedicated forums, mailing lists, and conferences. | F# has a growing community, with active support from Microsoft and various online resources. |
| Learning curve | Haskell has a steep learning curve, especially for programmers without prior experience in functional programming. | F# has a moderate learning curve, especially for programmers familiar with C# or other .NET languages. |
Common questions
Frequently Asked Questions
How do I convert Haskell to F#?
Paste your Haskell code into the input box, confirm the languages are set to Haskell and F#, and click Convert. CodeConvert AI analyzes your Haskell code and generates equivalent F# code in seconds, preserving the original logic and structure.
What are the main differences between Haskell and F#?
Haskell and F# 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 F# equivalent. See the comparison table below for the key differences between Haskell and F#.
Is the converted F# code accurate?
The AI produces high-quality F# code that preserves the behavior of your original Haskell code and follows F# conventions. It handles common patterns, data structures, and idioms for both Haskell and F#. For large or performance-critical code, review and test the F# output before using it in production.
Can I convert an entire Haskell project to F#?
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 F#. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
Can I convert F# back to Haskell?
Yes. CodeConvert AI converts in both directions, so you can convert F# to Haskell just as easily using our F# to Haskell converter. Try the F# to Haskell Converter
Is the Haskell to F# 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 F# without an account for up to 5 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.
