CodeConverter

About CodeConverter

CodeConverter is a single-purpose developer utility that translates a block of source code from one programming language into another. It supports more than 30 languages across the whole spread a working engineer is likely to meet: the mainstream set (JavaScript, TypeScript, Python, Java, C, C++, C#, PHP, Go, Ruby, Swift, Kotlin, Rust), the data and scientific languages (R, MATLAB, Julia), the JVM and functional families (Scala, Clojure, Groovy, Haskell, Elixir, Erlang, F#), the mobile and scripting tail (Objective-C, Dart, Lua, Perl), and legacy targets that matter for migration work specifically — Visual Basic, Fortran and COBOL. The interface is a two-pane browser editor: source language and code on the left, target language and converted output on the right, with syntax highlighting on both sides, a sample loader for trying the tool without pasting real code, and copy-to-clipboard on the result. Every conversion is retained in a per-account history that can be revisited or cleared, which makes the tool usable for an incremental port rather than only for one-off snippets. Paid accounts unlock advanced model selection and a larger context window, the latter being the constraint that determines how much code can be converted in a single pass. The site also runs a developer blog covering Python internals such as threading versus multiprocessing, lru_cache memoisation and the bisect module.
