Merge multiple bank statements into one CSV

A batch converter that hands back one file per statement has done the mechanical part of the work and left you the annoying part. Twelve CSVs still have to be opened, stacked and re-sorted before they're useful, and that's exactly where columns drift out of alignment and rows quietly go missing.

What most people want from a year of statements is one spreadsheet with every transaction in it, in the order things actually happened. That's what the merged download gives you: a single CSV containing every row from every statement in the batch, sorted by date, with a Source File column so nothing becomes anonymous along the way.

The balance column is deliberately left out of the merged file. A running balance describes one account's position at one moment, so interleaving balances from several statements gives you a column of numbers that looks meaningful and isn't. Where you need balances, use the per-file download.

At the foot of the merged file you get totals by source statement, totals by category, and a grand total, so the figures can be checked at a glance before the file goes anywhere near an accounting package.

Both outputs are available after every batch conversion. If the job really does call for separate files, whether that's different clients, different entities or different returns, the ZIP download is still there.
