hi,
I have a json file which i converted to using convertfrom-json and i want selected fields from it. I tried to pipeline the output to select-object but i was able to get the name and not other details. Below is my output of convertfrom-json and my script.

display_name   : TEL05
name           : TEL05
is_muted       : False
meta           : @{agent_checks=System.Object[]; timezones=System.Object[]; winV=System.Object[]; machine=AMD64; platform=win32;

host_name      : TEL05
has_metrics    : True

I want host name and agent_version(inside meta tag). how do i achieve this?

i tried below but did not worked.

$jsonstring = (Get-Content 'servers.JSON') | ConvertFrom-Json
$jsonstring.rows| select name, meta.agent_version

Maybe someone have a better answer.
But most likely it's due to the list not being a list of objects and/or part of it is not an object.
E.g. "Meta" is a nested hashtable and not an object.

To get around it you could e.g. run it through a foreach loop and pull the information
You need to replace $rows with e.g. $jsonstring.rows if you want to use that instead.

foreach($r in $rows)
{
    $info = @{Name = $r.name; 
              Agent_version = $r.meta.agent_version
             }
    
    $info
}
