How to add colors to Excel output file in Powershell - excel

Question

I have written a script to export specific registry keys and the sub keys inside it with the server ping response, but my scripts works as expected and I can able to export that to Excel as well.
But I need inputs or some help on how to add the colors to the Excel output column based on the value.
As Ex: in my script I will get ping response as true or false, for True I need to add green colour and for False I need to add Red color in my output, please help me to achieve this with my script.
CODE
## Get full list of servers
$Servers = GC -Path ".\Servers.txt"
## Loop through each server
$Result = foreach ($vm in $Servers) {
## Check the Ping reponse for each server
Write-Host "Pinging Server" $vm
$Ping = Test-Connection -Server $vm -Quiet -Verbose
if ($Ping){Write-host "Server" $vm "is Online" -BackgroundColor Green}
else{Write-host "Unable to ping Server" $vm -BackgroundColor Red}
## Check the Network Share path Accessibility
Write-Host "Checking Share Path on" $vm
$SharePath = Test-Path "\\$vm\E$" -Verbose
if ($SharePath){Write-host "Server" $vm "Share Path is Accessible" -BackgroundColor Green}
else{Write-host "Server" $vm "Share path access failed" -BackgroundColor Red}
Invoke-Command -ComputerName $vm {
## Get ChildItems under HKLM TCPIP Parameter Interface
Get-ChildItem -Path 'HKLM:\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces' | ForEach-Object {
Get-ItemProperty -Path $_.PSPath | Where-Object { $_.PsObject.Properties.Name -like 'Dhcp*' }
} | Select-Object -Property #{Name = 'ComputerName'; Expression = {$env:COMPUTERNAME+"."+$env:USERDNSDOMAIN}},
#{Name = 'Ping_Response'; Expression = {if($using:Ping) {'Pinging'} else {'Unable to ping'}}},
#{Name = 'Share_Path_Access'; Expression = {if($using:SharePath) {'Accessible'} else {'Not Accessible'}}},
DhcpIPAddress, #{Name = 'DhcpNameServer'; Expression = {$_.DhcpNameServer -split ' ' -join '; '}},
DhcpServer, #{Name = 'DhcpDefaultGateway'; Expression = {$_.DhcpDefaultGateway -join '; '}}
}}
$Result | Select-Object * -Exclude PS*, RunspaceId | Export-Excel -Path "$PSScriptRoot\TCPIP_Interface_Details.xlsx" -AutoSize -BoldTopRow -FreezeTopRow -TitleBold -WorksheetName TCPIP_Interface_Details

You can use the New-ConditionalText cmdlet to highlight cells containing the specified -Text with the color of our choice. The cmdlet can also take RGB colors. I encourage you to read the documentation on it, there are also many examples:
Get-Help New-ConditionalText
Since I don't have access to your $result object I can only give you an example of how you can do it using a simple example:
$result = 0..10 | ForEach-Object {
[pscustomobject]#{
ComputerName = 'Host' + $_
Ping_Response = ('Not Responding', 'Pinging')[($_ % 2)]
}
}
function RGB ($red, $green, $blue ){
return [System.Double]($red + $green * 256 + $blue * 256 * 256)
}
$fontGreen = RGB 0 97 0
$backGreen = RGB 198 239 206
$condProps = #{
Text = 'Pinging'
ConditionalTextColor = $fontGreen
BackgroundColor = $backGreen
}
$conditionalTrue = New-ConditionalText #condProps
$conditionalFalse = New-ConditionalText -Text 'Not Responding'
$props = #{
AutoSize = $true
InputObject = $result
Path = 'test.xlsx' # => Use your absolute Path here!
TableName = 'myTable'
TableStyle = 'Medium11'
WorksheetName = 'myWorkSheetName'
ConditionalText = $conditionalTrue, $conditionalFalse
}
Export-Excel #props
The end result should look something like this (unfortunately Google Sheets doesn't do it justice):
