Windows Power Shell rename files - powershell

Question

I am sort of new to scripting and here's my task:
A folder with X files. Each file contains some Word documents, Excel sheets, etc. In these files, there is a client name and I need to assign an ID number.
This change will affect all the files in this folder that contain this client's name.
How can do this using Windows Power Shell?
$configFiles = Get-ChildItem . *.config -rec
foreach ($file in $configFiles)
{
(Get-Content $file.PSPath) |
Foreach-Object { $_ -replace " JOHN ", "123" } |
Set-Content $file.PSPath
}
Is this the right approach ?

As #lee_Daily pointed out you would need to have different code to perform a find and replace in different file types. Here is an example of how you could go about doing that:
$objWord = New-Object -comobject Word.Application
$objWord.Visible = $false
foreach ( $file in (Get-ChildItem . -r ) ) {
Switch ( $file.Extension ) {
".config" {
(Get-Content $file.FullName) |
Foreach-Object { $_ -replace " JOHN ", "123" } |
Set-Content $file.FullName
}
{('.doc') -or ('.docx')} {
### Replace in word document using $file.fullname as the target
}
{'.xlsx'} {
### Replace in spreadsheet using $file.fullname as the target
}
}
}
For the actual code to perform the find and replace, i would suggest com objects for both.

Example of excel find and replace Search & Replace in Excel without looping?
I would suggest learning the ImportExcel module too, it is a great tool which i use a lot.

For Word Document : This is what I'm using. Just can't figure out how this script could also change Header and Footer in a Word Document
$objWord = New-Object -comobject Word.Application
$objWord.Visible = $false
$list = Get-ChildItem "C:\Users\*.*" -Include *.doc*
foreach($item in $list){
$objDoc = $objWord.Documents.Open($item.FullName,$true)
$objSelection = $objWord.Selection
$wdFindContinue = 1
$FindText = " BLAH "
$MatchCase = $False
$MatchWholeWord = $true
$MatchWildcards = $False
$MatchSoundsLike = $False
$MatchAllWordForms = $False
$Forward = $True
$Wrap = $wdFindContinue
$Format = $False
$wdReplaceNone = 0
$ReplaceWith = "help "
$wdFindContinue = 1
$ReplaceAll = 2
$a = $objSelection.Find.Execute($FindText,$MatchCase,$MatchWholeWord, `
$MatchWildcards,$MatchSoundsLike,$MatchAllWordForms,$Forward,`
$Wrap,$Format,$ReplaceWith,$ReplaceAll)
$objDoc.Save()
$objDoc.Close()
}
$objWord.Quit()

What If I try to run on C# ? Is anything else missing?
}
string rootfolder = #"C:\Temp";
string[] files = Directory.GetFiles(rootfolder, "*.*",SearchOption.AllDirectories);
foreach (string file in files)
{ try
{ string contents = File.ReadAllText(file);
contents = contents.Replace(#"Text to find", #"Replacement text");
// Make files writable
File.SetAttributes(file, FileAttributes.Normal);
File.WriteAllText(file, contents);
}
catch (Exception ex)
{ Console.WriteLine(ex.Message);
}
}
