New Column With Date (No other dates in source)

[Jaxon]

Hoping this isn't a complete noob question....

I have a data source (Excel file) that contains data but has no DATES Column to extract from.

In the Query Editor I'd like to:

1. Add a new column

2. Populate it with the date the data was refreshed OR the current date.

I've tried a bit using =NOW() and can do that outside of the query but would rather have it done upon the source refresh.

Appreciate any guidance.

Hi @Jaxon,

You could create a calculated column in Data view in Power BI Desktop by Today().

@Jaxon- Here is a very basic example:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlSKjQUA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Column1 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", Int64.Type}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Refresh", each DateTime.LocalNow())
in
    #"Added Custom"

Thanks much! Working through it now.

Sadly I have a dreaded refresh error I am trying to squash as well. (Fixed)
