If you receive "0 computers matched" "Attempting to upload computers to group x" -- With the result that no computers get added to the static group:

• A possible solution is to ensure your input file does not contain any extensions (.txt) in the filename!

Thank you @alexjdale and @cshepp11 , for sharing this script. I was able to make half way.
Do you also have script to remove computers from static group? Please share with me if you got one ready.
I was trying to modify the given script to remove computers in it but it was deleting the static group itself.

Thank you.

@Naren Take a look at the thread Script to add a device to a computer group? for an example of how to add a computer to an existing Static Group rather than replacing the contents of the group. Following the example in that thread you can use computer_deletions instead of computer_additions to remove computers from a group instead of adding them.

Thank you @sdagley for sharing the link. I was trying with two different scripts one to add multiple computers to static group other to remove from static group.
But when i was trying to execute the script it is adding or removing only the last entry from excel.
For example my .csv file has four computers and script is actually only reacting to the last one in it. @cshepp11

@sdagley any idea why its picking up only last line in the lookup, for example if I have 3 values, a, b, c in the list it will only process value c and leave other 2 items?

Hey, in order to run script in Big Sur, use xpath5.18
