VB or VB.NET? It really matters.

If you want to access single cell in worksheet, you can use ADO.NET[^] - OleDB[^].

Usage:

VB.NET

Dim connectionString As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=FullFileName.xlsx;Extended Properties='Excel 12.0;HDR=YES';"
Using connection As New OleDbConnection(connectionString)
      Using command As New OleDbCommand(selectSQL)
          command.Connection = connection
          Try
        connection.Open()
        Dim singleValue = command.ExecuteScalar()
        'you can use singleValue variable now ;)
        Catch ex As Exception
            Console.WriteLine(ex.Message)
        End Try
    End Using
End Using

For further details, see:
Obtaining a Single Value from a Database - ADO.NET | Microsoft Docs[^]
Retrieving Data Using a DataReader - ADO.NET | Microsoft Docs[^]

Or...
You can use EPPlus[^] NuGet package. See: How to Use EPPlus in VB[^]

VB (4-6) is basically VBA in todays world. You really need to update your app as it has died a long time ago and forms part of legends out there.

You also need to start thinking about going to .NET as your clients will also upgrade soon to WIN 11 and that means that all your code will crash, unless this is an app made for you many a year ago.

That being said, can you access the excel file?, is the code in VBA makro or VB4,5,6?, what error message do you get, what version of excel? etc etc.
