+  Description:
+    PowerShell script to convert any CSVs found in directory ($dirSource) that were created today -
+    (1) saves them as an XLSX,
+    (2) renames the first tab,
+    (3) moves the XLSX to the parent directory

+    $csv = $_.FullName
+    Write-Host "filePath ="$csv
+
+    $dirParent = (Get-Item $csv).Directory.Parent.FullName
