Hey James,
try that,,,
- export the AP inventory report
- open/import it in Excel
- delete the columns that you don't need - I assume you are only looking only for APname and BSSID
- save as csv
In that case the csv looks like that in notepad...
name,mac
_AP3825e,D8:84:66:0C:DE:B0
_Home_Demo,20:B3:99:BC:72:30
_Home_Demo,20:B3:99:BC:72:31
_Home_Fritz,D8:84:66:02:DD:90
_Home_Ron,D8:84:66:02:DF:E0
_Home_Ron,D8:84:66:02:DF:E1
Cheers,
Ron
