make Column categories as my column headers

Hi Anonymous ,

How about this.

Before:

After:

Here the code in Power Query M that you can paste into the advanced editor (if you do not know, how to exactly do this, please check out this quick walkthrough)

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WyszTLUgtKs7PU4rViVYqyMjPSwWzyjJTUvPBrNTcxMwcpdhYAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Channel = _t]),
    #"Transposed Table" = Table.Transpose(Source),
    #"Promoted Headers" = Table.PromoteHeaders(#"Transposed Table", [PromoteAllScalars=true]),
    #"Changed Type" = Table.TransformColumnTypes(#"Promoted Headers",{{"in-person", type any}, {"phone", type any}, {"video", type any}, {"email", type any}})
in
    #"Changed Type"

If this is not exactly what you were looking for, consider to use the pivot feature (Under the transform tab). Pivoting might help in case you have multiple columns next to your channel column.

Let me know if this helps 🙂
