Hi there, this feature isn’t available in Snoop yet.
But it’s one we’ll turn to after our next wave of money management features are ready - we’re targeting end of this year for these which will include spend reports, setting a custom month for spend analysis, and the addition of offline accounts to name a few.
We definitely see the value in the export feature and are keen to do it. Its just not made it to the top of the priority list yet.
Really appreciate your feedback @Stuad70
