Unable to export the data to CSV or Excel

I have written a script to check the nslookup for each server and export the details to Excel, but my script is looking but I am not able to export the output when I export I a getting empty data.

Please help me to export the data to Excel

CODE

## Loop through each server for Nslookup
foreach ($Server in $Servers)
{
    $Addresses = $null
    try {
        $Addresses = [System.Net.Dns]::GetHostAddresses("$Server").IPAddressToString
    }
    catch { 
        $Addresses = "Server IP cannot resolve"
    }
    foreach($Address in $addresses) {
        #write-host $Server, $Address
         $Server_Name = $Server
         $IP_Address = $Address                 
    } 
  } 
$result | Export-Excel -Path $FileName -AutoSize -BoldTopRow -FreezeTopRow -TitleBold -WorksheetName Server_Nslookup_Details

Your inner foreach loop is producing no output, just assigning values to the 2 variables ($Server_Name and $IP_Address):

foreach($Address in $addresses) {
    $Server_Name = $Server
    $IP_Address = $Address
}

You likely meant to construct a new object instead:

$result = foreach($Server in $Servers) {
    $addresses = try {
        [System.Net.Dns]::GetHostAddresses($Server).IPAddressToString
    }
    catch {
        "Server IP cannot resolve"
    }
    foreach($address in $addresses) {
        [pscustomobject]@{
            Server    = $Server
            IPAddress = $address
        }
    }
}

$result | Export-Excel ....
