    Is this what you try to achieve? You can use the custom column option and create the rules needed to do the transformation displayed in the tables. Hope this helps.

    Hi Anonymous ,

     

    Do you have another column identify the date column type? For example the date 2/1, If can be first day of february or the second day of january if you do not have any other column can identify the format.

     

    If you do have one, we can create a custom column depends on it easily in Power Query Editor.

     

     

    if [Type] = "MMDD" then Date.FromText([Date]) else Date.FromText([Date],"fr-SN")

     

     

     


    BTW, pbix as attached.

Thanks very much for your quick reply.  I neglected to mention the source file is live, meaning new data is added to it daily.  The solution you recommended would work for a static file but I'm hoping there's a solution that auto converts the new data coming in into a date format.

    Hi v-lid-msft ,

     

    I'm quite noob with the coding. How to make the "Type" column at Power Query which identifying the date format, either DDmm or mmDD?


    Appreciate your time and understanding. Thanks!
