Obtain row value based on index number in another column

[filiparibeiro]

Hello.

I'd like to add a custom column in power query that allows me to obtain the corresponding value in column 1 based on a certain Index value, ie., I'd like to obtain for index=12 the letter M for all rows in the new custom column. How do I do this?

Thanks in advance.

@Greg_Deckler But in the new custom column I want to obtain only the value in column 1 corresponding to index number = 12 ,ie,  a column where all the rows equal "M"...

Hi @filiparibeiro ,

Like this?

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("HcTHEYMwAACwXfxmCWoooYROfN5/De6kh2IMeUhZDIVLV67d+OPWnXsP/nr05NmLf169effh05dvP/6HlF4=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}}),
    #"Added Index" = Table.AddIndexColumn(#"Changed Type", "Index", 0, 1, Int64.Type),
    #"Step Name" = Table.SelectRows(#"Added Index", each [Index] = 12)[Column1]
in
    #"Step Name"
