How to convert the date to this format: [“Datum”].ToLocalTime().ToString(“dd-MM-yyyy”)?

Question

I need to convert the date used in the function below to this format:

["Datum"].ToLocalTime().ToString("dd-MM-yyyy");

This is the function:

$Global:selectProperties=@("Datum","00:00 - 07:59","08:00 - 16:59","17:00 - 23:59","Opmerkingen");
function ExportList($listName)
{
try
{
$listItems=(Get-PnPListItem -List $listName -Fields $Global:selectProperties).FieldValues
$outputFilePath="c:\Temp\" + $listName + ".xlsx"
$hashTable=@()
foreach($listItem in $listItems)
{
$obj=New-Object PSObject
$listItem.GetEnumerator() | Where-Object { $.Key -in $Global:selectProperties }| ForEach-Object{ $obj | Add-Member Noteproperty $.Key $_.Value}
$hashTable+=$obj;
$obj=$null;
}

    $hashtable | Export-XLSX $outputFilePath -Table -Autofit -Force
 } 
 catch [Exception] 
 { 
    $ErrorMessage = $_.Exception.Message        
    Write-Host "Error: $ErrorMessage" -ForegroundColor Red         
 } 

}

Answer 1

Is this what you're trying to do?

$Global:selectProperties = @("Datum", "00:00 - 07:59", "08:00 - 16:59", "17:00 - 23:59", "Opmerkingen");
function ExportList($listName) {
    try {
        $listItems = (Get-PnPListItem -List $listName -Fields $Global:selectProperties).FieldValues
        $outputFilePath = "c:\Temp\" + $listName + ".xlsx"
        $hashTable = @()
        foreach ($listItem in $listItems) {
            $obj = New-Object PSObject
            $listItem.GetEnumerator() | 
                ForEach-Object{
                    if ($Global:selectProperties -contains $_.Key){
                        if ($_.Key -eq 'Datum'){
                            $v = "{0:dd-MM-yyyy}" -f ([datetime]($_.Value)).ToLocalTime()
                        }
                        else{
                            $v = $_.Value
                        }
                        $obj | Add-Member Noteproperty $_.Key $v
                }
            $hashTable += $obj;
            $obj = $null;
        }
        $hashtable | Export-XLSX $outputFilePath -Table -Autofit -Force
    } 
    catch [Exception] { 
        $ErrorMessage = $_.Exception.Message        
        Write-Host "Error: $ErrorMessage" -ForegroundColor Red         
    } 
}

$Global:selectProperties=@("$datum.ToLocalTime().ToString("dd-MM-yyyy")","00:00 - 07:59","08:00 - 16:59","17:00 - 23:59","Opmerkingen");
I get an syntax error

Answer 3

$Global:seletProperties=@($_["Datum"].ToLocalTime().ToString("dd-MM-yyyy"),"00:00 - 07:59","08:00 - 16:59","17:00 - 23:59","Opmerkingen");
Doesn't work either

This is very hard

Answer 4

Hi,

What is the data type of the property "datum"? If it's DateTime you can try this

($hashtable.Datum.ToLocalTime()).ToString("dd-MM-yyyy")
