    Hello cathoms 

     

    I combined now both data into one table. The main table is basically created by checking the content of two columns.. basically creating the table from backwards until criteria a matching. Then extract with Table.SelectRows the value of your site and add it as new column. Here the complete code

     

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WUtKBoVidaCVn32BUAVRecGpRWWZyKpCblllUXIJTHZouzxBXIDsRCIjU4ZaZU5JahE8FLncVpybn56UAGYWlqcUlmfl5ILHSorLUSrBCQ1R9RqhcY1SuCSrXFJVrRrzznB09AvCGKy7flGRkFiF7BiRWlphTmgpW5wjkgTwEcqehIVwI5CmQW42M4EIgj4Hca2ysFBsLAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t, Column2 = _t, Colonna3 = _t, Colonna4 = _t]),
    Last = Table.RemoveFirstN(Source, each ([Column1]<>"Service" or [Column2]<>"third")),
    #"Promoted Headers" = Table.PromoteHeaders(Last, [PromoteAllScalars=true]),
    GetSite = Table.SelectRows(Source, each [Column1]= "SITE"){0}[Column2],
    AddSiteToTable = Table.AddColumn
    (
        #"Promoted Headers",
        "Site", 
        each GetSite
    )
    
in
    AddSiteToTable

    and this is the output

Thanks so much! To answer your questions and provide more detail, this particular report always has the same structure. Others are structured slightly differently with different number of useless top rows. At first I was just removing the top 37 rows but then my final query/table doesn't have the site name. What I am aiming for is a column with the site name (along with columns for service, date, etc.) that I can use to create and relate to a lookup table.

 

That is, I'm trying to go from the image in my original post to the following, except with the additional "site" column. Incidentally, I also need to add a colums for "unit", but I think I have a workaround for that problem.
