Common questions
Frequently Asked Questions
How do I convert F# to Delphi?
Paste your F# code into the input box, confirm the languages are set to F# and Delphi, and click Convert. CodeConvert AI analyzes your F# code and generates equivalent Delphi code in seconds, preserving the original logic and structure.
What are the main differences between F# and Delphi?
F# and Delphi differ in syntax, type system, standard libraries, and common idioms, so copying code line for line usually will not compile. The converter maps each F# construct to its closest Delphi equivalent. See the comparison table below for the key differences between F# and Delphi.
Is the converted Delphi code accurate?
The AI produces high-quality Delphi code that preserves the behavior of your original F# code and follows Delphi conventions. It handles common patterns, data structures, and idioms for both F# and Delphi. For large or performance-critical code, review and test the Delphi output before using it in production.
Can I convert an entire F# project to Delphi?
You can convert F# 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 F# to Delphi. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
Can I convert Delphi back to F#?
Yes. CodeConvert AI converts in both directions, so you can convert Delphi to F# just as easily using our Delphi to F# converter. Try the Delphi to F# Converter
Is the F# to Delphi converter free, and do I need to install anything?
