You can export data from Teamup using the bulk export feature, then work with the downloaded data in a CSV file.
However, you can also view data pertaining to a specific custom field anytime in Teamup, without exporting the data. Just use Table view!
Table view is a spreadsheet-like calendar layout that makes it easy to work with your calendar data and sort it by one or more custom fields.
Table view gives you the ability to view events over the precise date range you need, filter by one or more criteria, and sort the resulting data by one or more columns. Check out an interactive demo, then give it a try.
