VBA to open .CSV file and format Columns A and C as text

I have the code to open a .CSV file but when the file opens, it is converting some of the data, not all, to a date. As example, one of the cell values in column A is '5MAR'. When the file is opened, it is being converted to 03/05/2012. I need to leave this cell as '5MAR'. In other words I need to keep both columns in a text format. I did try to convert the columns to text after the file was open but it only proceeded to convert those cells to number. Any assistance appreciated. Thanks

    Prompt = "Select the data file to process."
    Path = Application.GetOpenFilename("Text Files (*.csv*), *.csv", , Prompt)
    
    Set wkbData = Workbooks.Open(Filename:=Path, ReadOnly:=True)

I tried to add the FieldInfo information but getting a 'Compile error' which indicates the 'Named argument not found' (FieldInfo)

    Prompt = "Select the data file to process."
    Path = Application.GetOpenFilename("Text Files (*.csv*), *.csv", , Prompt)
    
    Set wkbData = Workbooks.Open(Filename:=Path, FieldInfo:=Array(Array(1, 2), _
        Array(2, 1), Array(3, 2), Array(4, 1), Array(5, 1), Array(6, 1), _
        Array(7, 1), Array(8, 1), Array(9, 1), Array(10, 1)), ReadOnly:=True)
