Change a value in column of a CSV file

Question

I'm trying to find a way to change the value of all the entries in the 'Available Person' column in my csv file using PowerShell.

If the value is 'Y' it should be changed to '1' and if the value is 'N' it should be changed to ')':

Branch Number,      CoreID,     Available Person,      Workstation
8002,           FMD354800200,   Y,
8002,           FMD354800201,   Y,
8002,           FMD354800202,   N,
8002,           FMD354800203,   N,
8002,           FMD354800204,   Y,

Here's what I've tried:

$csv=Import-Csv user.csv' | $csv | %{ if($_.'Available Person' -eq "Y") {$_.'Available Person'="1"} } $csv|export-csv user1.csv' -NoTypeInformation

Answer 1

Here is some example code for how you might solve this with a Switch statement

$ImportedCSV = Import-CSV C:\user.csv
$NewCSV = Foreach ($Entry in $ImportedCsv) {
    Switch ($Entry."Available Person") {
        Y {$Entry."Available Person" = "1"}
        N {$Entry."Available Person" = ")"}
        default {Write-Error "$($Entry."Branch Number") has unexpected value for Available Person"}
    }
    $Entry
}
$NewCSV | Export-CSV C:\user1.csv -NoTypeInformation

Answer 2

try this

(Import-Csv C:\temp\LastAnalyse.csv | 
    %{$_.'Available Person'=if ($_.Path -eq 'Y') {'1'} elseif ($_.Path -eq 'N') {')'} else {$_.'Available Person'}; $_}) | 
        Export-Csv  C:\temp\LastAnalyse.csv -NoTypeInformation
