You can easily export all your transactions into an Excel spreadsheet. You can either export all of your transactions in your profile by clicking on the Actions drop-button and selecting Export Transactions from the list. You can also select multiple, specific transactions you'd like exported by checking the boxes to the left of those transactions and clicking the Export button on the highlighted bar at the top of the transactions list.
Be sure to use the various filtering options across the top of the transactions list to more quickly and effectively bring up similar transactions.
*Only 500 transactions are exported at a time.
