Mail merge: recorded macro in Word, could use some help to integrate it in Excel

Hi all!


I recorded a macro in Word using the mail merge wizard to print labels from an Excel file.

Here is the code I got from that:

Sub GenEtiq()
'
' GenEtiq Macro
'
'
    ActiveDocument.MailMerge.MainDocumentType = wdMailingLabels
    ActiveDocument.MailMerge.OpenDataSource Name:= _
        "Z:\Techniciens\SDPL\etiquettes\generation etiquette.xlsx", _
        ConfirmConversions:=False, ReadOnly:=False, LinkToSource:=True, _
        AddToRecentFiles:=False, PasswordDocument:="", PasswordTemplate:="", _
        WritePasswordDocument:="", WritePasswordTemplate:="", Revert:=False, _
        Format:=wdOpenFormatAuto, Connection:= _
        "Provider=Microsoft.ACE.OLEDB.12.0;User ID=Admin;Data Source=Z:\Techniciens\SDPL\etiquettes\generation etiquette.xlsx;Mode=Read;Extended Properties=""HDR=YES;IMEX=1;"";Jet OLEDB:System database="""";Jet OLEDB:Registry Path="""";Jet OLEDB:Engine Type=37;Jet OLEDB" _
        , SQLStatement:="SELECT * FROM `Sheet3$`", SQLStatement1:="", SubType:= _
        wdMergeSubTypeAccess
    ActiveDocument.MailMerge.Fields.Add Range:=Selection.Range, Name:= _
        "Departement"
    Selection.TypeParagraph
    ActiveDocument.MailMerge.Fields.Add Range:=Selection.Range, Name:="Salle"
    Selection.TypeParagraph
    ActiveDocument.MailMerge.Fields.Add Range:=Selection.Range, Name:= _
        "Endroit"
    Selection.TypeText Text:=" "
    ActiveDocument.MailMerge.Fields.Add Range:=Selection.Range, Name:="Point"
    Selection.WholeStory
    Selection.Font.Size = 8
    
    ActivePrinter = "\\beleprint001\BELEMDQA14"
    With ActiveDocument.MailMerge
        .Destination = wdSendToPrinter
        .SuppressBlankLines = True
        With .DataSource
            .FirstRecord = wdDefaultFirstRecord
            .LastRecord = wdDefaultLastRecord
        End With
        .Execute Pause:=False
    End With
End Sub

My question is: is there a way of making that a macro usable from the Excel file itself? I'm not familiar with VBA so I'm not sure where to start. I have a few tabs opened that are helping me with examples but it's still blurry..

Thank you in advance for your time and help.
