PowerShell get output in CSV format - powershell

Question

I am seeking help to get output in csv format. I have written powershell code and would want to tweak the output to get in csv format as shown in below pic.
$servers = Get-Content 'C:\Temp\listofservers.txt'
foreach ($server in $servers)
{
#DHCP
if (((Get-Service -ComputerName $server -ServiceName 'DHCPServer' -ErrorAction SilentlyContinue).Status) -eq 'Running')
{
if ((((Get-DhcpServerv4Scope -ComputerName $server | Get-DhcpServerv4Lease -ComputerName $server) | Measure-Object).Count) -ge 1)
{
Write-Host "DHCP present on $server and in use"
}
else
{
Write-Host "DHCP present on $server and not in use"
}
}
else
{
Write-Host("DHCP is not present on $server")
}
#Certificate authority
if (((Get-Service -ComputerName $server -ServiceName 'CertSvc' -ErrorAction SilentlyContinue).Status) -eq 'Running')
{
Write-Host "Certificate Authority is present on $server"
}
else
{
Write-Host "Certificate Authority is not present on $server"
}
}

Send all outputs to a custom object then export them:
$servers = get-content "C:\Temp\listofservers.txt"
$ExportPath = 'c:\temp\results.csv'
$Servers | ForEach-Object {
Write-Host "Checking $_"
# DHCP status
# Use Try....Catch to trap the errors - it's more robust than
# If...Then and prevents a wall of red text if something goes wrong
Try {
$DHCPStatus = Get-Service -ComputerName $_ -Name 'DHCPServer' -ErrorAction Stop
If ($DHCPStatus.Status -eq "Running") {
Try {
If ((((Get-DhcpServerv4Scope -ComputerName $_ -ErrorAction Stop | Get-DhcpServerv4Lease -ComputerName $_ -ErrorAction Stop) | Measure-Object).Count) -ge 1) {
$DHCPResult = "DHCP present on, in use"
}
Else {
$DHCPResult = "DHCP present, not in use"
}
}
Catch {
$DHCPResult = "DHCP present - error obtaining details: $_"
}
}
}
Catch {
$DHCPResult = "DHCP is not present"
}
#Certificate authority
Try {
If (((Get-Service -ComputerName $_ -ServiceName 'CertSvc' -ErrorAction Stop).Status) -eq "Running") {
$CAResult = "Certificate Authority is present"
}
}
Catch {
$CAResult = "Certificate Authority is not present"
}
[pscustomobject]#{ComputerName = $_;DHCP = $DHCPResult;CA=$CAResult}
} | Export-Csv -Path $ExportPath -NoTypeInformation

Use a hashtable to build your object, adding key/values for each property along the way. Then convert the hashtable to a [PSCustomObject] and output it capturing in a variable ($results). Finally, export it to csv using Export-Csv
$servers = Get-Content 'C:\Temp\listofservers.txt'
$results = foreach ($server in $servers) {
# Create hashtable to build object and add ComputerName property
$output = [ordered]#{ComputerName = $server }
#DHCP
if (((Get-Service -ComputerName $server -ServiceName 'DHCPServer' -ErrorAction SilentlyContinue).Status) -eq 'Running') {
if ((((Get-DhcpServerv4Scope -ComputerName $server |
Get-DhcpServerv4Lease -ComputerName $server) |
Measure-Object).Count) -ge 1) {
# add Dhcp property if present, in use
$output.Add('Dhcp', 'Present, in use')
}
else {
# add Dhcp property if present, not in use
$output.Add('Dhcp', 'Present, not in use')
}
}
else {
# add Dhcp property if not present
$output.Add('Dhcp', 'Not present')
}
#Certificate authority
if (((Get-Service -ComputerName $server -ServiceName 'CertSvc' -ErrorAction SilentlyContinue).Status) -eq 'Running') {
# add CA property if present
$output.Add('CA', 'Present')
}
else {
# add CA property if not present
$output.Add('CA', 'Not present')
}
# Convert hashtable to pscustomobject and output it
[PSCustomObject]$output
}
# output results to screen
$results
# export results to csv file
$results | Export-Csv -Path c:\temp\server_dhcp_ca_check.csv -NoTypeInformation
