Grouping column text values in Power Query
- Anonymous5 years ago
Hi KAURM
The source was done by Enter Data, so it was generated by Power Query. I have two queries, one is called rawData which is your sample data, the other is dimTable which is the output. To make things easier, you right click to open a blank query, and go to Advanced Editor, paste the whole code. Then you can see the steps which you can apply to your original data
To make it easier, I put them in one query, if you still can't get it, pm your email, I will send you the sample .pbix file
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("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", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [LocationID = _t, #"Characteristic 1" = _t, #"Characteristic 2" = _t, #"Characteristic 3" = _t, #"Characteristic 4" = _t, #"Characteristic 5" = _t, #"Characteristic 6" = _t, #"Characteristic 7" = _t]), #"Changed Type" = Table.TransformColumnTypes(Source,{{"LocationID", type text}, {"Characteristic 1", type text}, {"Characteristic 2", type text}, {"Characteristic 3", type text}, {"Characteristic 4", type text}, {"Characteristic 5", type text}, {"Characteristic 6", type text}, {"Characteristic 7", type text}}), #"Removed Columns" = Table.RemoveColumns(#"Changed Type",{"LocationID"}), #"Trimmed Text" = Table.TransformColumns(#"Removed Columns",{{"Characteristic 1", Text.Trim, type text}, {"Characteristic 2", Text.Trim, type text}, {"Characteristic 3", Text.Trim, type text}, {"Characteristic 4", Text.Trim, type text}, {"Characteristic 5", Text.Trim, type text}, {"Characteristic 6", Text.Trim, type text}, {"Characteristic 7", Text.Trim, type text}}), Custom1 = List.RemoveItems( List.RemoveNulls( List.Combine( Table.ToColumns( #"Trimmed Text"))),{""," "}), rawData = Table.FromList(Custom1, Splitter.SplitByNothing(), null, null, ExtraValues.Error), dimTable = Table.Distinct( rawData), #"Merged Queries" = Table.NestedJoin(dimTable, {"Column1"}, rawData, {"Column1"}, "dimTable", JoinKind.LeftOuter), #"Added Custom" = Table.AddColumn(#"Merged Queries", "Custom", each Table.RowCount([dimTable])), #"Removed Columns1" = Table.RemoveColumns(#"Added Custom",{"dimTable"}) in #"Removed Columns1" - 5 years ago
Here is another version with Grouping.
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("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", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [LocationID = _t, #"Characteristic 1" = _t, #"Characteristic 2" = _t, #"Characteristic 3" = _t, #"Characteristic 4" = _t, #"Characteristic 5" = _t, #"Characteristic 6" = _t, #"Characteristic 7" = _t]), #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(Source, {"LocationID"}, "Attribute", "Characteristics"), #"Removed Columns" = Table.RemoveColumns(#"Unpivoted Other Columns",{"LocationID", "Attribute"}), #"Trimmed Text" = Table.TransformColumns(#"Removed Columns",{{"Characteristics", Text.Trim, type text}}), #"Filtered Rows" = Table.SelectRows(#"Trimmed Text", each ([Characteristics] <> "")), #"Grouped Rows" = Table.Group(#"Filtered Rows", {"Characteristics"}, {{"Count", each Table.RowCount(_), Int64.Type}}), #"Sorted Rows" = Table.Sort(#"Grouped Rows",{{"Characteristics", Order.Ascending}}) in #"Sorted Rows" - 5 years ago
Hi KAURM ,
Check my sample .pbix file attached.
Best Regards,
KellyDid I answer your question? Mark my post as a solution!
Hi Anonymous
That's great thank you!
I have changed the data source to #"characteristics in the last 12 months analysis" but now the following error occurs
Hi KAURM
It is not just to change the Source, you need to go through the steps and understand how they work. The error might not happen at the last step, you need to click each step to understand it. My guess is it happened in the second step as your sample data was entered but your real source may be reading from somewhere, you need to transform it to the same shape then go next step. I will send you my sample .pbix file.
