xlwings Lite new WINGMAN function - some usage patterns: python sandbox, stats, cleaning, bucketing, judging

Published: February 14, 2026

Felix Zumstein released the new function just yesterday. Similar to =COPILOT in Excel. Tried out some common patterns. Wanted to get a feel for it.

Works wonderfully well.

Sharing my test file so you can see the usage: Google Sheets - WINGMAN test file

Quick example patterns

Some quick example patterns that I have tried out:

• Having the LLM use its python sandbox
• Passing full range, adjacent ranges and single rows
• Getting back data in pre-specified structure so that it fits snugly next to my main table
• Data cleaning - judgment based (non deterministic)
• Categorize customer profile based on data points - judgment based

Setup

Setup is straightforward - Settings - Local - Wingman. I tried it out with both OpenAI and Gemini. Works smooth. And option to bring custom model. So potentially you can use say an OpenRouter also...
