Small things that come up after a statement becomes a spreadsheet. Like the converter and the format converters, they run in your browser. No upload, no account.
- Find duplicate transactionsSpot rows that repeat before they become double payments. Choose which columns count as the same.
- Merge statement exportsStack several months of CSV exports into one sheet under a single header, with mismatched files flagged.
These exist because they are the steps that follow a conversion in real work, not to fill a page. If something you do by hand every month is missing, it is probably worth adding.
Why these two
Converting a statement is the loud problem. These are the two quiet ones that show up right afterwards, and both are the kind of thing people do by hand in a spreadsheet and get wrong at volume.
Duplicates come from overlapping exports. Ask for January to March, then March to May, and March arrives twice. In a file of two hundred rows the repeat is invisible, and if that file feeds anything that pays invoices, it pays twice. Merging is the same story from the other side: a year of bookkeeping arrives as twelve separate downloads and has to become one sheet before anyone can total a column.
Both run the way the converter does. The file is read in this page, on your machine, and nothing is sent anywhere. There is no account and no cap, because there is no server bill to cover.
There is deliberately no categoriser here, and no spending chart. Sorting transactions into categories is a judgement call about your own money, and a tool that guesses wrong quietly is worse than no tool. That job belongs in whatever you already use for accounting, once the data is clean enough to import.
