If the running balance on your Banco Santander-Chile statement does not add up row by row, that is exactly the kind of mismatch Convert·Into is built to catch rather than pass through silently. The running balance printed on a statement is the single most reliable checkpoint in the entire document. Convert·Into reads that figure exactly as it appears and verifies it against the sum of the extracted transactions, line by line. The process does not trust the extracted total until it matches the printed closing balance. When a row breaks the tally, a deposit misread as a withdrawal or a transposed digit that shifts the running figure by a penny, the engine flags that specific row rather than rejecting the whole file. You can review the flagged line, correct the value, and resume without redoing any other work. The check catches the kinds of errors that silent extraction misses, so the output lands in your ledger already reconciled to the source document.
If a transaction description on your Banco Santander-Chile statement is long enough to wrap across two or three lines, it still needs to land in a single row once converted. Transaction descriptions that run long and wrap across multiple lines are a frequent source of split rows in manual conversion. Convert·Into groups the wrapped lines back into a single transaction record before populating the table, so a multi-line description stays in its own row instead of contaminating the entries below it. The engine identifies the pattern by recognising where the amount column and date column repeat, using those fixed points to reassemble the text block.
When your Banco Santander-Chile statement arrives as a scan or a photo of the page rather than a clean export, the numbers on it are just pixels until they are extracted. Scanned and photographed statements add noise: skewed text, uneven lighting, marks on the page. Convert·Into applies OCR to read the image, then runs the same running-balance check it uses on clean digital files. Anything the scan misread breaks the arithmetic, and the verification step flags the row for your attention. The file does not need to be a pristine electronic original to produce a reliable export.
