[PowerShell] Export Feuilles excel vers PDF

Bonjour,

Voici ci-dessous un script powershell que j'ai tenté de compléter afin de générer automatiquement 1 fichier PDF par feuilles excel:

Code:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
Get-ChildItem . -Filter CRA*.xlsm | Foreach-Object {
  $wb=$excel.workbooks.open($_.FullName)
  $ws = $wb.Worksheets.Item("CRA")
  $ws.Activate()
  $FullName = ("CRA_") + ($wb.FullName) #Pour formater le nom du fichier PDF
  $ws.PrintOut("","", 1,"False","PDFCreator","True",$FullName)
  $ws.PrintOut()
  $ws = $wb.Worksheets.Item("PC")
  $ws.Activate()
  $ws.PrintOut()
  $FullName = ("PC_") + ($wb.FullName) #Pour formater le nom du fichier PDF
  $ws.PrintOut("","", 1,"False","PDFCreator","True",$FullName)
  $wb.Close($false)
}

A l'exécution j'ai les erreurs suivantes:

Code:

J'avoue ne pas maitriser du tout PowerShell, quelqu'un pourrait-il me venir en aide?

Merci
