What makes bank statement PDF conversion trustworthy enough to use?

I’m building BankExcelConverter for bookkeepers, freelancers, and small finance teams that need to move transactions from PDF statements into Excel or CSV.

The difficult part is not simply extracting rows. A converter can create a polished spreadsheet while still missing a transaction, reversing a sign, or combining the wrong columns.

My current approach is review-first:

• Preserve the source page for every transaction

• Flag low-confidence and ambiguous rows

• Check running and closing balances

• Keep questionable rows visible instead of silently dropping them

• Let users review the result before CSV or Excel export

I’d love to learn how people currently verify converted statements:

1. Which errors cost you the most time?

2. Do you manually reconcile the closing balance?

3. Which information would help you trust—or reject—an extracted row?

4. What statement layouts cause the most trouble?

Bank statement formats vary widely, so I’m especially interested in real workflow problems rather than claims of perfect accuracy.
