Convert a single row into multiple rows, depending on values in a specific column in Power Bi - powerbi

Question

I have rows of data which can have information in multiple columns that I need to extract and convert into an individual row for each.
E.g.
Original table
Headers are:
Product Code | Description | Location 1 | Location 2 | Location 3
and I need to convert it to:
Product Code | Description | Location
Some products will be available in multiple regions.
If a product is available in Germany and France, there may be an DE in the Location 1 column, and an FR in the Location 2 column, while the location 3 column will be blank.
I need to convert it so that there is a single location column with corresponding entries for each region that product had.
Desired output table
Is there a way to automate this in Power Bi?

Answer 1

Select the Code and description columns then
UnpivotOtherColumns
Remove the blank entries
Remove the Attribute column
Not sure how you want your results sorted, but you could easily add a sorting algorithm to below.
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUfJILAGSLq5AAoRidaKVjICM4OTEojQg7RYElwVJGQMZ7jn5ZanFQEaoN5KC2FgA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Product Code" = _t, Description = _t, #"Location 1" = _t, #"Location 2" = _t, #"Location 3" = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Product Code", Int64.Type}, {"Description", type text}, {"Location 1", type text}, {"Location 2", type text}, {"Location 3", type text}}),
//Select Product Code and Description Columns
// Then "Unpivot other Columns
#"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Changed Type",
{"Product Code", "Description"}, "Attribute", "Location"),
//Remove the blank locations and the "Attrubute" column
#"Filtered Rows" = Table.SelectRows(#"Unpivoted Other Columns", each ([Location] <> "")),
#"Removed Columns" = Table.RemoveColumns(#"Filtered Rows",{"Attribute"})
in
#"Removed Columns"
