Profile

Hey HN! I built Banker.so, an AI agent that actually understands and writes Excel files.I upload spreadsheets to ChatGPT/Claude all the time. CSV files work okay. But .xlsx files with formulas, multiple sheets, and pivot tables? They break constantly.The problem: LLMs process data sequentially (1D), but spreadsheets are 2D structures. Cell B5 has meaning because it's in column B, row 5. Formulas reference ranges like A1:C10. Current AI tools miss these spatial relationships because they are designed for humans’ visual understanding.What fails today:- Complex Excel files with multiple linked sheets - Formulas and named ranges get corrupted or ignored - Pivot tables and conditional formatting

The company sits in the show hn launch segment, where it competes on its core product or service.

Its current recorded stage is Show HN launch.
