How do I match a value in multiple rows in CSV - powershell

Question

I have a csv file that contains
Full Name
Some Column
Access Required
John Smith
Stuff
System 1
John Smith
something
System 3
Bob Villa
other
Application 4
Bob Villa
more
Application 6
Doug Mack
stuff
System 2
I'd like to import this csv and match based upon one "full name" at a time (that I'm getting from a variable ie:Full Name) so that I get an out which I'll send as the body of an email that is:
Full Name: John Smith
Access Required: System 1
Access Required: System 3
Then I will run script again looking for Bob Villa and get:
Full Name: Bob Villa
Access Required: Application 4
Access Required: Application 6
I think I could do this with a bunch of "if statements" but I'm wondering if there's a way to parse the csv based upon "full name" and then list all the entries found in the "Access Required" column for each row that "full name" is found?
Note: I don't want anything from any other columns (and there could be lots of them), just want the contents of "Access Required"
Thank you!

Answer 1

Import the csv in a variable and select the data for the user by the full name:
$data = Import-Csv -Path 'path\to\input.csv'
# example select John Smith
$user = 'John Smith'
$selection = $data | Where-Object {$_.'Full Name' -eq $user}
if (#($selection).Count) {
# format as you like, for simplicity
$table = $selection | Format-Table -AutoSize | Out-String
# in a html mail embed $table inside '<pre>' tags, so
# it will display in a monospace font.
# $body = "<pre>$table</pre>"
}
else {
Write-Warning "Could not find $user"
}
Just import once, keep variable $data and repeat the part that starts with $user = ... for each new user

I was able to solve the issue using a combination of Foreach, an if statment and then switch.
$source = '\somesoure.csv'
$csv = import-csv $source
Foreach($row in $csv){
$personName = $row."Full Name"
$accessRequired = $row."Access Required"
if ($personName -eq $mayInputNameVariable){
//do some code stuff such as write to a column
switch ($accessRequired){
"System 1" {
$System1 = "Access Required: System 1`n"
}
//do it for all switch values
}
$emailBody = "Full Name:$personName`n" + $system1 + $system2 ...etc
$csv | Export-CSV $source -NoTypeInformation
Thanks folks!
