Can't change date data type

Hi, 

 

My months are written in text format (January), and when trying to change the format of the column to 'Date' PBI throws up this error, "DataFormat.Error: We couldn't parse the input provided as a Date value. 

Details: 

     January"

 

Could someone advise on how to correct this please? 

 

Thanks

Hi @deanbland 

I'm assuming you just have the month name in a column?  If so you can add a Custom Column and use Date.FromText to create a date.

Here's a sample PBIX file.

 

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45W8krMK00sqlSK1YlWcktNKoJzfBOLkjPALMeCoswcqBhEzqs0LxXKyIGIOJamlxaXgJnBqQUlqblJqUVgnn9yST6M7ZdfhpBwSU2GcmIB", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Months = _t]),
    #"Added Custom" = Table.AddColumn(Source, "Custom", each Date.FromText("1 " & [Months] & " 2020")),
    #"Changed Type" = Table.TransformColumnTypes(#"Added Custom",{{"Custom", type date}})
in
    #"Changed Type"

We can't transfer month name to date. We can only transfer date to month name

you can create a calendar table

https://docs.microsoft.com/en-us/dax/calendar-function-dax

transfer to month name

month = FORMAT('Table'[date],"mmmm")
