Replace values in matrix/table based on reference table
Hi all,
I'm trying to create a table with a specific strcuture and im not sure what the best way is to create it, i hope someone could help.
My situation is that i have a table with codes, and a table with a certain amount, per code. i need to recreate the table with the same Areas and column headers, and replace the codes in the cells with the corresponding values (from the Sums table), and where there is no value, put 0 (or null)
Eventually there will be a table with around 1000 separate cells (and separate codes from table 1)
Is this possible to do in power query and if so what options are there?
Thanks
Just copy the next code and past it into advance editor.

Step 1: Unpviot table 1Step 2: Merge the Table 2 and result of unpviot table 1
Step 3: remove extra column
Step 4: Pivot the result table
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WcixKTVRwVNJRMgRiIyA2VorVgQo7AbmmQGwGxOYIYWcg1wKILUG6DJRiYwE=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Area = _t, #"round 1" = _t, #"round 2" = _t, #"round 3" = _t]), #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(Source, {"Area"}, "Attribute", "Value"), Source2= Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WcixKTVRwVNJRMgJiQ3OlWB2omBOQbwoSN0QVMwepM0GIOQP5lkBsbKYUGwsA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Area = _t, Cluster = _t, Count = _t]), #"Merged Queries" = Table.NestedJoin(Source2, {"Area", "Cluster"}, #"Unpivoted Other Columns", {"Area", "Value"}, "New", JoinKind.LeftOuter), #"Expanded New" = Table.ExpandTableColumn(#"Merged Queries", "New", {"Attribute", "Value"}, {"Attribute", "Value"}), #"Removed Columns" = Table.RemoveColumns(#"Expanded New",{"Cluster", "Value"}), #"Sorted Rows" = Table.Sort(#"Removed Columns",{{"Attribute", Order.Ascending}}), #"Pivoted Column" = Table.Pivot(#"Sorted Rows", List.Distinct(#"Sorted Rows"[Attribute]), "Attribute", "Count") in #"Pivoted Column"result

Thank you Omid, much appreciated this helps!
if the combined value of Area and Cluster in Table2 is unique.
=Table.ReplaceValue(Table1,each [Area],"",(x,y,z)=>Table2{[Area=y,Cluster=x]}?[Count]? ??x,List.Skip(Table.ColumnNames(Table1)))
