Add column with sepecific cell value
I want create new column A16_2 base on value of first row A16 which use flexible way:
| Index | A16 | A16_2 |
| 0 | 3500 | 3500 |
| 1 | null | 3500 |
| 2 | null | 3500 |
I use Custom function from Edit Query in Excel.
I try some way like that:
- if [A16] = null then [A16]{0} else [A16]
- List.Average([A16])
But It NOT WORK. Could someone guide me how to create new column base on specificed value of 1 column?
Hi Anonymous
When you call [A16], it is not a list, so what is your logic?
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlDSUTI2NTBQitWJVjIEcvJKc3LAHCM4JxYA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Index = _t, A16 = _t]), #"Changed Type" = Table.TransformColumnTypes(Source,{{"Index", Int64.Type}, {"A16", Int64.Type}}), #"Added Custom" = Table.AddColumn(#"Changed Type", "yourNewColumn", each if [A16]=null then #"Changed Type"[A16]{0} else [A16]), #"Added Custom1" = Table.AddColumn(#"Added Custom", "Custom", each List.Average(#"Added Custom"[A16])) in #"Added Custom1"
