Code Translator - Convert Code Between Programming Languages

Paste a function, a script or a file of up to 10,000 characters and get it back in another language, written the way that language is written, with a list of every place the behaviour may differ. Python to TypeScript, JavaScript to Go, VBA to Python, jQuery to plain JavaScript, and most other pairs.

What a Good Translation Keeps, and What It Cannot

A line-by-line port produces code that compiles and reads like a foreign accent. The translator aims for the idiomatic version instead: a list comprehension becomes a map or a reduce, a Python dict becomes a typed record, error codes become exceptions or Result values, whichever the target language expects. Comments come along, translated. Nothing is added that the source did not have, which is why you will not get tests or a main function you did not ask for.

The caveats list is the honest part. Integer sizes and overflow, floating point formatting, string encoding, mutability of default arguments, the order of dictionary keys, threads versus an event loop, and libraries that simply do not exist on the other side: every one of those is named so you know where to test. Snippets and single files work best; for a whole project, translate one module at a time. The same translator is available to scripts and AI agents through the ToolForte REST API and MCP server as translate_code.

How the Code Translator Works

  1. 01Paste the code: a function, a script or a single file of up to 10,000 characters.
  2. 02Name the target language, and the source if it is not obvious. Add wishes such as a runtime version or a framework.
  3. 03The translation keeps the behaviour and uses the target language's idioms, standard library and naming.
  4. 04Read the choices made and the caveats, which name every place where behaviour may differ, and test there first.

When to Use This Tool

When a team moves from one language to another and wants a first draft of each module. When a Stack Overflow answer is in the wrong language. When a VBA macro has to become a Python script, or a jQuery snippet plain JavaScript. When you read one language well and want to understand code in another by seeing it in yours.

Frequently Asked Questions

Can it translate a whole project?→
One module at a time, up to 10,000 characters each. A project has structure, build files and dependencies that need a human decision; the translator handles the code inside.
Is the translated code guaranteed to work?→
No. It keeps behaviour as far as the target language allows, and the caveats list tells you exactly where to test. Read them before running anything.
Can I call this from a script or an AI agent?→
Yes. The translator is available through the ToolForte REST API and MCP server as translate_code.
