Show HN: Statement Proof – PDF bank statement to CSV, proved or refused

Converts a PDF bank statement to CSV — and proves the result against the statement's own balances. If it doesn't add up, you get told which row, not a file you'd have trusted.

Nothing is stored. The file is read in memory and discarded.

Any converter looks good on a clean statement. This is the one that separates them — download it and put it through anything you like, including this.

985.50 − 80.25 = 905.25. The statement prints 915.25. Every value on its own is perfectly plausible; only the arithmetic disagrees. That is exactly what a misread looks like, and it is invisible to anything that only reads the page.

Drop it in above and you get told “Row 3 does not agree with the balance printed beside it on the statement” — and no CSV, because there is no correct CSV to give you.

We put this same file through two other converters. Both returned a CSV. One of them displayed “all checks passed”, and the CSV it produced contained an amount that appears nowhere on the statement. We are not naming them, because the file is right there — check for yourself.
