To download a CSV for your Card Transactions:
Start by clicking on the Card Icon of the toolbar which will take you to your Cards Page.
Once there, select the "View All" button next to the Recent Transactions section on the overview page.
Once you're on the View All page, you can filter by entering a specific date range, search a specific merchant/amount, and/or select a specific status.
Once you have your filters set, click the blue EXPORT CSV button in the upper right-hand corner.
Note: You can also click into a specific card for just that card's transactions
Note: By selecting transactions that only have a Settled status you will be given a running balance of your account in the CSV.
