Your Excel files are processed locally and never leave your computer . Is it safe? Local Models (Ollama, LM Studio): Your data never leaves your machine. 100% private. Cloud Models (OpenRouter, ChatGPT): Only the precise results of operations (counts, sums, formulas) and metadata (column names) are sent to the model. The bulk raw data remains on your disk. --- 🤨 Why This Exists The Problem: Most Excel tools for AI dump raw spreadsheet data into the agent's context. This floods the context window, slows everything down, and the AI can still miscalculate or get confused in large datasets. This Project: Think SQL for Excel. Your AI agent composes atomic operations ( filter and count , aggregate , group by ) and gets back precise results — not thousands of rows. The agent analyzes data without seeing it .
