Pivot Column in Query
Hey All!
I'm trying to make a column "Data Source" From rows to columns
But I get the following message?
Can anyone help?
Hi netanel ,
The sample in case seems like not your fact table, right? The error means that PowerQuery is expecting a textual input but receives nothing. You need to make sure it receives a textual input. Try replacing empty fields by "null" or "empty". This can be done either manually within the source (transform the column or create a new column) or within PowerQuery.
About how to replace null values with custom values in PowerQuery:

Hey netanel ,
you can just select the "Data Source" Column and then chose "Pivot Column".
In the upcoming dialogue, choose "Sum" as aggregation type for the values:
Then the result will be as you desired:
Check here my example:
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45W8vRT0lEyNFKK1YGxjZHYJkhsUyS2GRLbHMz2Dw0BcSyQOZZIHCMDZI4hMscImQO0PRYA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Data Source" = _t, Amount = _t]), #"Changed Type" = Table.TransformColumnTypes(Source,{{"Data Source", type text}, {"Amount", Int64.Type}}), #"Pivoted Column" = Table.Pivot(#"Changed Type", List.Distinct(#"Changed Type"[#"Data Source"]), "Data Source", "Amount", List.Sum) in #"Pivoted Column"If you need any help please let me know.If I answered your question I would be happy if you could mark my post as a solution ✔️ and give it a thumbs up 👍Best regardsDenisBlog: WhatTheFact.biFollow me: twitter.com/DenSelimovic- netanelPost Prodigy
