how to use if/else statement to replace a value in PowerShell - azure

Question

function Get-vmstatus {
# Sign into Azure Portal
connect-azaccount
# Fetch the Virtual Machines from the subscription
$azureVMDetails = get-azvm
# Fetch the NIC details from the subscription
$azureNICDetails = Get-AzNetworkInterface | ? { $_.VirtualMachine -NE $null }
#Fetching Virtual Machine Details
$virtual_machine_object = $null
$virtual_machine_object = #()
#Iterating over the NIC Interfaces under the subscription
foreach ($azureNICDetail in $azureNICDetails) {
$azureVMDetail = $azureVMDetails | ? -Property Id -eq $azureNICDetail.VirtualMachine.id
$vm_status = get-azvm -ResourceGroupName $azureVMDetail.resourcegroupname -name $azureVMDetail.name -Status
$vm_tags = ($azureVMDetail.Tags.values) -join ';'
$vmsize = Get-AzVMSize -VMName $azureVMDetail.Name -ResourceGroupName $azureVMDetail.ResourceGroupName | ? { $_.Name -eq $azureVMDetail.HardwareProfile.VmSize }
$OsDisksize = $azureVMDetail.StorageProfile.OsDisk.DiskSizeGB
#Fetching the private IP
$private_ip_address = ($azureNICDetail.IpConfigurations | select-object -ExpandProperty PrivateIpAddress) -Join ';'
#VM Details export
$virtual_machine_object_temp = new-object PSObject
$virtual_machine_object_temp | add-member -membertype NoteProperty -name "Name" -Value $azureVMDetail.Name
$virtual_machine_object_temp | add-member -membertype NoteProperty -name "VCPUs" -Value $vmsize.NumberOfCores
$virtual_machine_object_temp | add-member -membertype NoteProperty -name "Status" -Value $vm_status.Statuses[1].DisplayStatus
$virtual_machine_object_temp | add-member -membertype NoteProperty -name "Memory" -Value $vmsize.MemoryInMB
$virtual_machine_object_temp | add-member -membertype NoteProperty -name "Disk" -Value $OsDisksize
$virtual_machine_object_temp | add-member -membertype NoteProperty -name "Comments" -Value $vm_tags
$virtual_machine_object += $virtual_machine_object_temp
}
$virtual_machine_object | Export-Csv "C:\Users\mouj\Desktop\Inventory\Final Scripts\VM_details_$(get-date -f dd.MM.yyyy).csv" -NoTypeInformation -Force
}
After running the script the Status of the Azure VMs are shown as VM running, VM stopped, VM deallocated. Now i want to replace the VM running with "Active" and VM stopped, VM deallocated with "Offline". How can i do with conditional statement or is there any other way to do it ? Thanks in advance

Use Add-Member to add a ScriptProperty - a dynamic property that can reference the value(s) of other properties on the object:
$virtual_machine_object_temp | Add-Member -MemberType ScriptProperty -Name State -Value { if($_.Status -eq 'Running'){ 'Active' }else{ 'Offline' } }
Now, whenever you look at the new State property, it will resolve to Active whenever the Status property is Running, otherwise Offline
