Export-CSV only gets the "Length" - excel

Question

when I try to export to a CSV list, I only get all number for "Length"
.Count property until the split point is reached, then split the CSV array to a new file with a new name that will be used from this point on. What might be the issue?
$RootFolder = Get-Content "c:\DRIVERS\myfile.txt"
foreach ($arrayOfPaths in $RootFolder){
$csv = $arrayofPaths -replace '^\\\\[^\\]+\\([^\\]+)\\([^\\]+).*', 'C:\output\Company_name_${1}_${2}.csv'
$csvIndex = 1
$maxRows = 1000000
$rowsLeft = $maxRows
Get-ChildItem $arrayOfPaths -Recurse | Where-Object {$_.mode -match "d"} | ForEach-Object {
#$csv = $_.FullName -replace '^\\\\[^\\]+\\([^\\]+)\\([^\\]+).*', 'C:\output\Company_name_${1}_${2}.csv'# <- construct CSV path here
$path = $_.FullName
$thisCSV = Get-Acl $path | Select-Object -Expand Access |
Select-Object #{n='Path';e={$path}}, IdentityReference, AccessControlType,
FileSystemRights |
ConvertTo-Csv
if ($thisCSV.count -lt $rowsLeft) {
$thisCSV | Export-Csv $csv -append -noType
$rowsLeft -= $thisCSV.count
} else {
$thisCSV[0..($rowsLeft - 1)] | Export-Csv $csv -append -noType
$csvIndex++
$csv = $csv -replace '\.csv$', "$csvIndex.csv"
if ($thisCSV.count -gt $rowsLeft) {
$thisCSV[$rowsLeft..($thisCSV.count - 1)] | Export-Csv $csv -append -noType
}
$rowsLeft = $maxRows - ($thisCSV.count - $rowsLeft)
}
}
}

Export-CSV is built to take PSCustomObjects as input, not lines of text.
$thisCSV = Get-Acl $path | Select-Object -Expand Access |
Select-Object #{n='Path';e={$path}}, IdentityReference, AccessControlType,
FileSystemRights |
ConvertTo-Csv
The output of this line will be something like:
#TYPE Selected.System.Security.AccessControl.FileSystemAccessRule
"Path","IdentityReference","AccessControlType","FileSystemRights"
"c:\test","BUILTIN\Administrators","Allow","FullControl"
At least three lines, an array of string. What properties does an array of string have?
PS C:\> 'a','b' | Get-Member -MemberType Property
TypeName: System.String
Name MemberType Definition
---- ---------- ----------
Length Property int Length {get;}
Length. The only property you see in the CSV, because Export-CSV is exporting all the properties, and that's the only property.
Fix: Remove | ConvertTo-CSV from the Get-ACL line, leave your custom objects as custom objects and let the export handle converting them.
(This should also fix the counting, because it's not counting 3+ lines of text while trying to export 1+ line of data every time).
