Yes. Nearly all reports can be generated/downloaded to your computer in CSV (Excel) format by following these steps:
Visit your [My Agency] tab or [Admin] tab.
Go to the [Reports] sub-tab and select the report type you wish to generate.
On the 1st reporting screen, select "CSV" from the top-right (optionally filter by certain parameters like Date, Categories, etc.) and click [Next].
On the 2nd reporting screen, select the data you wish to include in the export and click [Request Report].
Once report finishes, download the CSV file and open in Microsoft Excel or a similar spreadsheet program.
