Show HN: Zunorm – BYOM Spreadsheet Editor

Hi HN,

I built Zunorm, a simple spreadsheet editor where you can make simple, targeted edits using your own models.

Instead of uploading your data to a closed AI service, Zunorm lets you:

- Bring your own model (via OpenRouter or local Ollama)

- Apply natural language edits directly to spreadsheet cells

What it’s good for -

- Cleaning or reformatting columns

- Quick AI-assisted edits without writing formulas or scripts

- Supports only CSVs for now

Still early, feedback welcome, especially around UX and real-world spreadsheet workflows.

Thanks for checking it out
