Reporting a file that converts wrongly
The most useful report describes the layout of the file: the column names, how dates look (for example 05/11/2026 or 2026-11-05) and how money out is shown (a minus sign, brackets, or a separate column).
Please do not email real bank statements. If a sample helps, send a copy with the descriptions and amounts changed, keeping the layout the same.
Ideas for new tools
If you regularly fight with a file format, tell us what you start with and what you need at the end. That is how new tools get chosen.
