01
The problem I saw
A bank statement may look readable but still resist reconciliation. Dates, descriptions, deposits, withdrawals, and balances can sit in the wrong columns. A clean export can also hide a missing opening balance.
02
What I built
The public workspace loads a sample statement with three extracted rows. It separates date, description, withdrawal, deposit, balance, review state, and type. A review queue flags the missing opening balance. A person can edit values, show the source PDF, and export XLSX, CSV, DOCX, PDF, QBO, review JSON, or a ZIP review pack. In the static build, document parsing and optional caches run in the browser.
03
What I learned
A usable conversion has two outputs: the file and the reason to trust or review it. The sample makes the missing balance visible instead of calling the document finished.
PAIN POINTS
What the product addresses
- Manual re-keying across file formats
- Extraction tools that stop before usable output
DECISIONS
Decisions that shaped it
- Keep money columns as numbers in spreadsheet exports.
- Show a balance check and review state before download.
- Let edits recalculate the balance trail immediately.
- Provide diagnostic data without statement text, rows, or filenames.
LEFT OUT
What I deliberately did not build
- A one-click export that hides uncertain rows and missing balances.
MEASURES
What I would measure
- Documents that reach export without an unresolved critical flag.
- Rows edited after comparison with the source page.
- Balance trails that reconcile after review.
- Files that need OCR or manual correction by source format.
EVIDENCE AND BOUNDARIES
What this note is based on
- Visible on extractmint.iangoh.com on 21 July 2026: the three-row sample, balance check, review queue, source-PDF control, export options, local caches, and privacy-safe diagnostic description.
- The first-party GitHub README describes this as a static prototype. I did not upload a private statement or verify OCR accuracy, financial accuracy, QuickBooks compatibility, or production security.
