Vector Sheets Framework™
Our proprietary AI framework that transforms how LLMs understand complex spreadsheets — reading logic, not just text.
Powering Model Maestro — the formula-level forensics engine at the core of Diligenz AI™.
Eight techniques for reading a spreadsheet as logic.
Structural-Anchor Extraction
Identifies key structural anchors within spreadsheets to maintain layout context while removing redundant data.
Inverted-Index Translation
Creates dictionary-like indexes of non-empty cell contents, significantly reducing token count through intelligent merging.
Data-Format-Aware Aggregation
Groups adjacent cells sharing the same data types or number formats for optimized LLM representation.
Multi-Sheet Cross-Reference
Understands inter-sheet relationships, following formulas and cell references spanning multiple tabs.
Complex Structure Handling
Handles merged cells, pivot tables, and conditional formatting — elements that break competitor solutions.
Large File Token Management
Compression at scale for massive enterprise files (10+ sheets) that would otherwise hit API token limits.
Multi-Format Input
Supports .xls, .xlsx, .csv, PDF, and images via OCR for comprehensive document processing.
State & Security Management
Persistent environment with infrastructure for handling sensitive financial data through sanitization and secure processing.
The logic layer behind Model Maestro.
VSF™ is the technical foundation that allows Model Maestro to treat a financial model as a network of logic rather than a collection of numbers — tracing formula dependencies, detecting structural inconsistencies, and compressing enterprise-scale files without losing fidelity.
