Convert an American Express CSV to QBO, OFX or QFX

American Express activity downloads list charges as positive and payments and credits as negative — the opposite of how a bank or QuickBooks sees money out. Importing them as-is turns every purchase into a deposit.

Bankfold detects this pattern (positive purchases, negative "payment — thank you" lines) and flips the signs automatically, showing a notice so you can undo it. It also selects the credit card account type, so the file is written as a card statement.

Steps

1. Download your activity from Amex as CSV or Excel.
2. Drop it into Bankfold and confirm the "signs flipped" notice and the preview.
3. Download QBO for QuickBooks, QFX for Quicken, or OFX for Xero and others.
