How to Properly Export to CSV Using Powershell - windows

Question

May I know how to properly export this script to CSV?
Try {
Invoke-Command -scriptblock {Get-EventLog System -After "7/8/2017" -Before "07/28/2017" |
Where-Object {$_.EventID -eq "50" -or $_.EventID -eq "51" -or $_.EventID -eq "55" -or $_.EventID -eq "57" -or $_.EventID -eq "6008"} |
FT -Property Machinename, TimeWritten, EntryType, Source, EventID, Message -AutoSize -wrap } -computername $computer -ErrorAction Stop
}
Catch {
Write-Host $Computer "Error/RDC Problem" -ForegroundColor Red
}
Result:
Export-CSV command is not working properly when added at the end. It outputs a different set of data.

Answer 1

Formatting cmdlets like Format-Table don't just change the way the object is displayed, it changes the object itself into something that will display how you want it to. This is part of why it's commonly recommended not to use the formatting cmdlets in scripts or functions.
Instead, you should use the Select-Object cmdlet to limit the number of properties passed to Export-Csv.
Invoke-Command -ComputerName $computer -ErrorAction Stop -ScriptBlock {
Get-EventLog System -After "7/8/2017" -Before "07/28/2017" |
Where-Object { 50, 51, 55, 57, 6008 -contains $_.EventID } |
Select-Object -Property MachineName, TimeWritten, EntryType, Source, EventID, Message
}

Answer 2

try this
Try {
Invoke-Command -scriptblock {Get-EventLog System -After "7/8/2017" -Before "07/28/2017" |
Where EventID -in ("50", "51", "55", "57", "6008") |
select Machinename, TimeWritten, EntryType, Source, EventID, Message } -computername $computer -ErrorAction Stop |export-csv "c:\temp\result.csv"
}
Catch {
Write-Host $Computer "Error/RDC Problem" -ForegroundColor Red
}
or may be simply like this :
Try
{
Get-EventLog System -After "7/8/2017" -Before "07/28/2017" -ComputerName $computer |
Where EventID -in ("50", "51", "55", "57", "6008") |
select Machinename, TimeWritten, EntryType, Source, EventID, Message |export-csv "c:\temp\result.csv" -NoType
}
Catch
{
Write-Host $Computer "Error/RDC Problem" -ForegroundColor Red
}
