SheetCompass: Hierarchical Relation Graphs for Agentic Spreadsheet Reasoning

Spreadsheets pack in complex, spatial, and cross-referential structure that gets destroyed when LLMs flatten them into plain text, crippling automated analysis. SheetCompass instead builds explicit relation graphs capturing structural links within and across worksheets, paired with a memory system that keeps relevant context available to reasoning agents. This lets AI agents navigate spreadsheets more like human analysts do --- spatially and relationally. Applications include automated financial modeling, business intelligence tools, spreadsheet auditing, and any enterprise workflow where AI agents need to reliably interpret and manipulate real-world Excel files.
