Is it possible to speed up an Excel query within PowerShell?

Question

I am currently using the following query to add a specific row (with 10 columns) from an Excel spreadsheet (~1500 rows and hosted on SharePoint) to an array in PowerShell.

$connection = New-Object System.Data.OleDb.OleDbConnection

$connectstring = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=$Source;Extended Properties='Excel 12.0 Xml;HDR=YES'"; $connection.ConnectionString = $connectstring

$connection.open()

$cmdObject = New-Object System.Data.OleDb.OleDbCommand

$query = "Select * from [Sheet1$] 
WHERE [Sheet1$].[Test] = '$Test'"
$cmdObject.CommandText = $query
$cmdObject.CommandType = "Text"
$cmdObject.Connection = $connection

$oReader = $cmdObject.ExecuteReader()

[void]$oReader.Read()
    $Global:oData = New-Object PSObject
    $oData | Add-Member NoteProperty List1    $oReader[0]
    ...
    $oData | Add-Member NoteProperty List10   $oReader[9]

$oReader.Close()
$cmdObject.Dispose()
$connection.Close()
$connection.Dispose()

This works absolutely fine, however it is often quite slow. Is there any way in which I could speed up the query? I can't add the entire excel sheet into an array, as the data changes throughout the day and is queried regularly.

I've found other questions, such as Speed up reading an Excel File in Powershell however that doesn't seem relevant to this particular issue.

Appreciate any help.
