Powershell: How to import csv find a value in a row, list of the column data and over-write some coumns? - powershell

Question

I think it's easiest to show what I have and what I'm trying to get as an output instead of me trying to verbalize what I'm doing and what I've tried.
Input is a csv that contains:
Full Name
Color
Access Type
Access ID
John Smith
Blue
Full_Acccess
jsmith
John Smith
Blue
Partial_Access
John Smith
Red
No_Access
Bill Bob
Red
Full_Access
Bill Bob
Pink
Access_1
Lisa Smith
Green
Access_2
I will call this script each time and look for "Full Name". Then if "Access ID" is empty, I want to populate Access ID (from a variable) and write out the "Output" below to a variable and send that as the body of an email.
So run script, look for "Full Name". In this case, it will look for and finds "Bill Bob" and since Access ID is empty, it will write "Rob Bob" (a variable value) to "Access ID" but also send email body of output below
OutPut:
Full Name: Bill Bob
Color: Red, Pink
Date: 03-21-2021
Access_Type: Full_Access, Access_1
Access ID: Rob Bob
So it's showing a unique Full Name (not all three rows), but also all values of Color and Access Type for "Full Name"
I've got this working using:
Import-CSV |Group-Object -Propert 'Full Name' | Select-Object #{Name = "Full Name"; Expression = {(_.Group.'Full Name' | Select-Object -Unique)}},
#{Name = "Access Type"; Expression = {($_.Group.'Access Type' | Select-Object -Unique) -join ","}},
#{Name = "Color"; Expression = {($_.Group.'Color' | Select-Object -Unique)}},
#{Name = "New Name"; Expression = {($_.Group.'New Name' | Select-Object -Unique)}} |
Where-Object {$_.'Full Name' -eq $PersonName}
Where I'm stuck:
Script will be called and imports CSV and searches for "Bill Bob". Then I want to list all the columns for Bill AND write the new Access_ID value back into the CSV.
Then I call the script again and look for John Smith, and then again for Lisa Smith, etc..
Thanks all!

I think I got what you were going for, here's what I would use:
Function Get-UserAccess ([string]$fullname,[string]$csvpath){
# Export your output
$csv = Import-CSV $csvpath
$filtered = $csv | Where-Object {$_.'Full Name' -eq $fullname}
$output = [pscustomobject]#{
'Full Name' = $fullname
'Access Type'=($filtered.'Access Type' | Select -Unique) -join ','
'Color' =($filtered.'Color' | Select -Unique) -join ','
'Access ID' =($filtered.'Access ID' | Select -Unique) -join ','
}
# check if Access ID is empty on Full_Access users
if (-not $output.'Access ID' -and
($output.'Access Type' -split ',') -contains 'Full_Access') {
# Set your AccessID here
$AccessID = Read-Host "Enter a new access ID for $fullname"
# Update the Access ID in the csv:
$entry = ([Collections.Generic.List[Object]]$csv).findIndex({
$args[0].'Full Name' -eq $fullname -and
$args[0].'Access Type'-eq 'Full_Access'})
$csv[$entry].'Access ID' = $AccessID
Write-Host "Updating $csvpath with new access ID for $fullname"
$csv | Export-Csv $csvpath -Force -NoTypeInformation
# Return output with Access ID
$output.'Access ID' = $AccessID
return $output
} Else { Return $output }
}
And some example usage with the data from your question:
PS C:\> Get-UserAccess 'Bill Bob' 'C:\temp\temp.csv' | fl
Enter a new access ID for Bill Bob: Rob Bob
Updating C:\temp\temp.csv with new access ID for Bill Bob
Full Name : Bill Bob
Access Type : Full_Access,Access_1
Color : Red,Pink
Access ID : Rob Bob
PS C:\> Get-UserAccess 'John Smith' 'C:\temp\temp.csv' | fl
Full Name : John Smith
Access Type : Full_Access,Partial_Access,No_Access
Color : Blue,Red
Access ID : jsmith,
