Date data changing from custom to general in a single column

I have data from US were the dates format change in a column.


An example is for a date 10/01/2020 03:50 excel is recognising that it is Custom and the text is right indented

then just below that the date 9/30/2020 14:50 is left indented and excel is calling this format general.

I suspect for the second date the fact that there is a 0 missing before the 9 is an issue.

I am working in GMT

Is there a method to format the 9/30/2020 date?

Hello @osabhaois 


check out this solution with Table.TransformColumns

    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjTQNzDUNzIwMlAwMLYyNVCK1YlWUrDUNzaACBqagAVjAQ==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t]),
    Transform = Table.TransformColumns
                each DateTime.From(_,"en-US"),
                type datetime
