# VaultSheet

> 100% browser-local PDF bank statement and financial ledger converter to Excel (.xlsx), CSV, QuickBooks (.qbo Checking/Savings & Credit Card, 3-Column & 4-Column Web Connect CSV), Xero CSV, OFX, and JSON.

## Core Architecture
- Zero server uploads: all PDF parsing runs strictly in browser RAM via a local `pdfjs-dist` Web Worker plus a deterministic coordinate table reconstructor.
- Mathematical audit verification: verifies `Opening Balance + Credits - Debits == Closing Balance` down to exact cents and flags row-level running balance mismatches and cross-statement duplicates inline.
- Multi-line stitching: merges wrapped wire details, card suffixes, and FX notes directly into the parent transaction row.
- Localized number/date parsing: supports US (`1,234.56`), European (`1.234,56`), accounting parentheses `(450.25)`, and `CR/DR` credit/debit notation.
- Supported export formats (8): Multi-sheet Excel (`.xlsx`), Standard CSV, QuickBooks Web Connect (`.qbo` Checking/Savings & Credit Card `<CREDITCARDMSGSRSV1>`), QuickBooks 3-Column CSV, QuickBooks 4-Column CSV, Xero CSV, OFX (`2.2`), and JSON.
