' Add a workbook Set xlWB = xlApp.Workbooks.Add Set xlSheet = xlWB.Worksheets(1)

It's important to clarify a common point of confusion:

Dim xlApp As Object Dim xlWB As Object Dim xlSheet As Object ' Create Excel instance (no reference needed) Set xlApp = CreateObject("Excel.Application") xlApp.Visible = True

How to do Late Binding:

This allows your VB6 program to work with any installed version of Excel (2000 through 365) without needing a specific library reference.

Newer versions are backwards compatible. If you have Office 2010, 2013, 2016, 2019, or 365, reference the latest library you see (e.g., 16.0). Your code will still work with older Excel files.

' Do something xlSheet.Cells(1, 1).Value = "Hello from VB6"

' Clean up Set xlSheet = Nothing xlWB.Close False Set xlWB = Nothing xlApp.Quit Set xlApp = Nothing
