Vector Sheets Format™
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.
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.
Put VSF™ to work on your deal.
