# Which AI Coder should you use for xlwings Lite (Python in Excel)?

**Beginners:** Gemini 2.5 Pro on aistudio.google.com. Free, simple, 1M context. Covered in my guides at [xlwings-lite.tigzig.com](http://xlwings-lite.tigzig.com/)

**Heavy iterative work:** Use proper AI coders that handle large codebases with incremental edits - Claude Code, Cursor, VS Code with Copilot, Gemini CLI.

**My default for xlwings Lite:** Gemini CLI. Nearly all my xlwings Lite work runs here. Simple setup. Strong free tier, 1M context.

**Help your AI Coder:** upload the AI Coder Instruction File I share in my xlwings guides. It is designed to make AI Coder's job easier and output reliable.

## Why not ChatGPT?

It works fine for quick iterations, but on longer codes it forgets to check the instruction file consistently and the context window fills up too fast.

## Claude?

Best AI coder by a wide margin. I use both Claude Code as well as Cursor. But both have been clamping down on message limits - so I toggle between AI Coders depending upon task and messaging quota remaining and typically keep them for more complex pieces.

## Gemini CLI?

Not Claude-level, but excellent for xlwings Lite, Python FastAPI backends, simpler HTML-JS UI's. With the Instruction File it works out superbly well for xlwings Lite. And the free tier makes it practical. This is my current setup too.
