Hi @Anonymous,

Here is the expanded table from the sample JSON string with custom query steps, you can try it if suitable for your requirement.

Full query:

let Source = Json.Document(File.Contents("C:\Users\xxxxx\Desktop\test.json")), #"Converted to Table" = Record.ToTable(Source), #"Expanded Value" = Table.ExpandListColumn(#"Converted to Table", "Value"), #"Expanded Value1" = Table.ExpandRecordColumn(#"Expanded Value", "Value", {"v"}, {"v"}), #"Expanded v" = Table.ExpandRecordColumn(#"Expanded Value1", "v", {"f"}, {"v.f"}), #"Unpivoted Columns" = Table.UnpivotOtherColumns(#"Expanded v", {"Name"}, "Node", "Value"), #"Added Custom" = Table.AddColumn(#"Unpivoted Columns", "Custom", each Table.Transpose(Table.FromList(List.Transform([Value],each Record.Field(_,"v"))))), #"Expanded Expand" = Table.ExpandTableColumn(#"Added Custom", "Custom", {"Column1", "Column2"}, {"Group", "Sales"}), #"Removed Columns" = Table.RemoveColumns(#"Expanded Expand",{"Value"}) in #"Removed Columns"
