Show HN: I integrated Ollama into Excel to run local LLMs

I built an Excel add-in that connects to Ollama, so you can run local LLMs like Llama3 directly inside Excel. I call it XLlama.

You can use it like a regular formula: =XLlamaPrompt("Is Excel a database") or run it on an entire range.

No API calls. No cloud. No subscriptions. Everything runs locally.

It’s useful for quick tasks like extracting names, emails, or phone numbers from text, or for doing light data analysis without leaving Excel.

Would love feedback, especially from people who use Excel daily.

I'm an Excel nerd. Started out as a business analyst and now build Excel templates and add-ins for small businesses and data folks.

I made an integration for ChatGPT in Excel right when it came out. Shared it on YouTube. Many users liked the idea, but were hesitant, as spreadsheets often include financial or other sensitive data they don’t want to send to OpenAI.

So I built XLlama to fix that. It runs everything locally using Ollama. It’s useful if you want to analyze text or data without leaving Excel. Also works well for tasks like extracting names, emails, or phone numbers from text.

Hope it might be also helpful to you.
