Barclays gives you a reasonably tidy CSV with a single signed amount, which is a good start. The friction is elsewhere: the descriptive text is spread across more than one field, and the account identifier column travels along for the ride.
Open the account, find the statement or transaction download option, choose your date range and pick CSV. Barclays also offers QIF and OFX formats; if your accounting software takes OFX directly, that route skips conversion entirely.
Typically a row number, the date, an account identifier, a signed amount (money out negative), a subcategory such as the payment method, and a memo holding the payee text. Dates are UK day-first.
