Saving Excel Files as TSV using Macro

This should work, just change the path

Sub test()

    ActiveWorkbook.SaveAs Filename:="C:\Users\User\Desktop\Book1.tsv", _
        FileFormat:=xlText, CreateBackup:=False

End Sub

This should work, and re-Enable the current real workbook

Sub tsv()
 ' save the current fileName for re-save later
    BookName = ThisWorkbook.Path & "\" & ThisWorkbook.Name
    ' select the good Sheet.Range
    Sheets("TSV-Sheet").Range("A1:N25").Select
    ' dont display alert when already exist
    Application.DisplayAlerts = False

    ' save TSV file
    ActiveWorkbook.SaveAs Filename:="C:\Users\User\Desktop\Book1.tsv", FileFormat:=xlText, CreateBackup:=False

    ' change the sheetName modified by previous SaveAs
    ActiveSheet.Name = "TSV-Sheet"

    ' Resave the real WorkBook (because the current workbook is *.TSV)
    ActiveWorkbook.SaveAs Filename:=BookName, FileFormat:=xlOpenXMLWorkbookMacroEnabled, CreateBackup:=False
    Application.DisplayAlerts = True
End Sub
