The Spend page shows you all the Apps for which you have Transaction spend (not contract spend) in your Vendr account.
For each of these Apps, it will show you the sum of all Transaction spend for that app in one of three views. You can select your view option from the View by button on the left.
On the right hand side there is a Download button to export whatever view you are currently looking at.
