PowerShell -- Import csv, reformat date values, export csv - powershell

Question

I have a large volume of CSV records that have a date column that needs to be reformatted. The format in the source files is "MM/dd/yyyy hh:mm". The format I need to change to is "yyyy-MM-dd". I've tried a few different things, and I've been able to get the two pieces to work (import and transform, or export), but not both together.
Sample data
Date Created,ID,Email Address,First Name,Last Name
3/15/2019 14:56,some-string,email#address.com,first,last
3/15/2019 13:56,some-string,email#address.com,first,last
Import and transform (w/ Write-Host to confirm reformat)
Import-Csv .\foo.csv |
ForEach-Object {
$_."Date Created" = [datetime]::Parse($_."Date Created").ToString('yyyy-MM-dd')
Write-Host $_."Date Created"
}
Import and Export (w/ no transform)
Import-Csv foo.csv |
Select-Object "Date Created", ID, "Email Address", "First Name", "Last Name" |
Export-Csv -NoTypeInformation foo-new.csv
I've tried this to combine the two pieces, but I end up with an empty CSV file
Import-Csv foo.csv |
ForEach-Object {
$_."Date Created" = [datetime]::Parse($_."Date Created").ToString('yyyy-MM-dd')
} |
Select-Object "Date Created", ID, "Email Address", "First Name", "Last Name" |
Export-Csv -NoTypeInformation foo-new.csv
Any help to smash these together, so I have my reformat and my successful export, would be greatly appreciated.

Answer 1

You need to use a calculated property with Select-Object
Try
Import-Csv foo.csv |
Select-Object #{Name = 'Date Created'; Expression = { '{0:yyyy-MM-dd}' -f [datetime]$_.'Date Created' }},
* -ExcludeProperty 'Date Created' |
Export-Csv -NoTypeInformation foo-new.csv

Answer 2

Easiest way to go about this is using a calculated property:
Import-Csv -Path C:\users\Abraham\Desktop\csvDate.csv |
Select-Object -Property #{
Name = "DateCreated"
Expression = {
([datetime]$_."Date Created").ToString("yyyy-MM-d")
}
}, ID, "Email Address", "First Name", "Last Name" # | Export-Csv ...
As for what you tried. . .you're basically de-selecting all your properties when piped to Foreach-Object then trying to select what's not already there; hence why you get an empty csv.
