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