Add empty column to table in power query

Hi all,

I want to add an extra column to a table in power bi query. All rows must be empty, just a column with only a column name.

Most probably I have to use the 'add column' option, but I need some guidance.

Thanks upfront for you help!

John

    Click the 'Custom Column' from the Add column tab and in the box either type

     

    null

    or

    ""

    depending on the result you want. 

     

    Here is sample code for advanced editor and/or formula bar if you want: 

     

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlSK1YlWMkImjZViYwE=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Existing Column" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Existing Column", Int64.Type}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Null Column", each null),
    #"Added Custom1" = Table.AddColumn(#"Added Custom", "Blank Column", each "")
in
    #"Added Custom1"

    Hi Anonymous,

     

    on Power Query,

    Add Custom Column,

    Change Custom name to your desired column name,

    Add in body ""

    then Ok

     

    Hope this helps.

    I'm not sure if I'm having the same problem. But all I want to do is add new columns to my power query database because we added columns to our original template. Now some excel

    files that have been merged into the database aren't showing the newly added columns information. How can I add new columns without associating them with columns already on the database? I just need to add new columns so that the information from the excel files will match the headings in the database and make everything populate because right now it's not.

      If you have added new columns to your source file in this case is a excel sheet. Though the new columns that you added are empty you have to refer while importing in power query and you should not create a new blank column. Go back to your Power Query and check the headings if the new blank column is exported hen all the problem might resolve.

       

      Let me know if my understanding is correct.

       

      Thanks,
