I guess you want to convert it in to a csv..
GC C:\input.txt | Select -Skip 1 | % {
$test = $_ -split "\|" | %{$_.Trim()}
	New-Object PSObject -Property @{
	ID = $test[0]
	Name = $test[1]
	}
} | Export-Csv C:\out.csv -nti

Open in new window


But if you want exactly same as you written then try..
$outfile = "C:\Temp\out.txt"
Set-Content $outfile $null
GC c:\temp\input.txt | Select -Skip 1 | % {
$test = $_ -split "\|" | %{$_.Trim()}
Add-Content $outfile "ID=$($test[0]),Name=$($test[1])"
}

Open in new window

Is there any way can I get column heading ID,name automatically without hard code. Sometimes I have two columns and sometimes I have 3 or more columns and I may not know column name upfront.
Example:
I may have
id|name|description
1|test|test1
2|test2|Test3

Sometime I may have
id|name|description|fundname
1|test|Test1|XXX
2|test2|Test3|YYY

Does Powershell have you tied up in knots?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Somewhat clumsy, but working:

Param (
[string]$originalName = "\path\to\file"
[string]$copyName = "\path\to\copy"
[Int32]$noColumns = 2
)
$arrHeader = @()
$header = (Get-Content $originalName -TotalCount 1).Split("|")
for ($i=0; $i -lt $noColumns; $i++) {
  $arrHeader += $header[$i]
}

$text = ""
foreach ($line in get-content $originalName) {
  $list = $line.Split("|")
  for ($i=0; $i -lt $noColumns; $i++) {
    $text = $text + $arrHeader[$i] + "=" + $list[$i] + ","
  }
  $text = $text.Substring(0, $text.Length - 1)
  $text = $text + "`n"
}
echo $text > $copyName

Open in new window


Save it as whatever.ps1 and run it as whatever.ps1 <original_file> <target_copy> <number_of_columns>

Try this.. Script should dynamically detect the headings..
$outfile = "C:\Temp\out.txt"
$inputfile = "c:\temp\input.txt"

Set-Content $outfile $null

$head = (GC $inputfile | select -First 1) -split "\|" | %{$_.Trim()}

GC $inputfile | Select -Skip 1 | % {
$test = $_ -split "\|" | %{$_.Trim()}
 $Data = @()
	for ($i=0; $i -lt ($head | Measure).Count; $i++) {
	  $Data += "$($head[$i])=$($test[$i])"
	}
 Add-Content $outfile $($Data -join ",")
}
