You can use the Worksheets object like this:

Private Sub Command1_Click()
Dim XL As Excel.Application

    'Open Excel
    Set XL = New Excel.Application
    XL.Visible = True
    
    'Create a new workbook
    XL.Workbooks.Add
    
    'Put data on the second sheet
    XL.Worksheets("Sheet1").Range("A1").Value = "Hello 1"
    XL.Worksheets("Sheet2").Range("B2").Value = "Hello 2"
    XL.Worksheets("Sheet3").Range("C3").Value = "Hello 3"
    
    'Get data from worksheets
    MsgBox XL.Worksheets("Sheet1").Range("A1").Value

    XL.Quit
    Set XL = Nothing
End Sub
