Hi Becky! If you are currently using our universal CSV integration, you should be able to see split transactions and the specific accounting categories associated with them today in the export. In order to see the different accounting categories associated with the split transactions, you should export as Journal Entries. This option should give you a more detailed breakdown of fields compared to download CSV option, including the accounting categories, receipt information, debit/credit information, etc.
Let me know if that works for you!
