Methodology

What the converter checks.

We normalize formats, keep source rows visible, and block exports when the meaning of a transaction is not clear.

Dates

Ambiguous dates such as 01/02/2026 require a format choice. Mixed formats produce row-level errors instead of silent guesses.

Currency symbols, separators, parentheses, and debit/credit columns are normalized with decimal arithmetic. Totals are recalculated before export.

Every non-empty source row is either represented in the preview or reported with a source row number and rule ID.

Potential duplicates are a warning, not a deletion instruction. The tool never removes transactions automatically.
