Shift Values to the Left for certain rows

Hi Einomi ,

Suppose we have:

You may consider creating three new conditional columns. like this:

= if [Data.Column6] = null then [Data.Column7] else [Data.Column6]

= if [Data.Column6] = null then [Data.Column8] else [Data.Column7]

= if [Data.Column6] = null then null else [Data.Column8]

Then remove and rename the columns.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUTICYmOlWJ1oJQQnFgA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Data.Column6 = _t, Data.Column7 = _t, Data.Column8 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Data.Column6", Int64.Type}, {"Data.Column7", Int64.Type}, {"Data.Column8", Int64.Type}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each if [Data.Column6] = null 
then [Data.Column7] else [Data.Column6]),
    #"Added Custom1" = Table.AddColumn(#"Added Custom", "Custom.1", each if [Data.Column6] = null 
then [Data.Column8] else [Data.Column7]),
    #"Added Custom2" = Table.AddColumn(#"Added Custom1", "Custom.2", each if [Data.Column6] = null 
then null else [Data.Column8]),
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom2",{"Data.Column6", "Data.Column7", "Data.Column8"}),
    #"Renamed Columns" = Table.RenameColumns(#"Removed Columns",{{"Custom", "Data.Column6"}, {"Custom.1", "Data.Column7"}, {"Custom.2", "Data.Column8"}})
in
    #"Renamed Columns"
