Another way:
Go to APs/Devices list page
Go to folder 'Top' (or a level that encompasses all devices you're looking into)
Click the link next to the folder drop down for 'expand folders to show all APs/Devices'
Then above the device list table, customize the columns using 'choose columns' -> remember to click 'save' at top of the list when you have the columns you want / in the order you want
Then next to 'choose columns' is 'export CSV' -> this will give you a CSV file of the data which you can put into spreadsheet doc
This does change the user view that you've logged in as, so if you want to save yourself some time from resetting your column viewing preferences, create a temporary admin account that you can delete after you get the CSV you want.
