You can easily create a text report with nsradmin (see below). However, it is not really Excel ready:

C:\>nsradmin > D:\clients.txt

. type: nsr client

[option hidden]

[show name, saveset, ... whatever_you_want_to_see ...]

p

p

q

C:\>

  - Select the columns you want to see in your report

  - Mark all lines and copy their content with ^C

  - Paste the input in a text editor

  - Prepare the output
