PowerShell CSV parsing Import from CSV and cast properties to correct type
Example
By default, Import-CSV imports all values as strings, so to get DateTime- and integer-objects, we need to cast or parse them.
Using Foreach-Object:
> $listOfRows = Import-Csv .\example.csv
> $listOfRows | ForEach-Object {
#Cast properties
$_.DateTime = [datetime]$_.DateTime
$_.Integer = [int]$_.Integer
#Output object
$_
}
Using calculated properties:
> $listOfRows = Import-Csv .\example.csv
> $listOfRows | Select-Object String,
@{name="DateTime";expression={ [datetime]$_.DateTime }},
@{name="Integer";expression={ [int]$_.Integer }}
Output:
String DateTime Integer
