Filter out Text in Date column

Question

Hi,&nbsp;I want to filter out all the values that do not look like dates in a column in Power Query. Here is the sample data.&nbsp;N/A6/1/201912/4/20187/1/2020TBC10/26/2021Nov_18&nbsp;In the above example, I want to filter out N/A, TBC, and NOV_18. is there an automated way to do that in power query?&nbsp;&nbsp;Regards,Anuj

You could just change the data type to Date, then remove errors.&nbsp;let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45W8tN3VIrViVYy0zfUNzIwtARzDI30TUA8CzDPHCxlZADmhDg5Q5QY6BuZgYQNwVy//LJ4kPJYAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type date}}),
    #"Removed Errors" = Table.RemoveRowsWithErrors(#"Changed Type", {"Column1"})
in
    #"Removed Errors"

Hello&nbsp;itsmeanuj&nbsp;,
&nbsp;
you could remove it from power query by clicking the drop down arrow for the filtering and uncheck it. thus it won't show.

Hi&nbsp;itsmeanuj&nbsp;
You can put the following code to advanced editor in power query
let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45W8tN3VIrViVYy0zfUNzIwtARzDI30TUA8CzDPHCxlZADmhDg5Q5QY6BuZgYQNwVy//LJ4kPJYAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Value = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Value", type text}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each try Value.Is(Date.FromText([Value]),type date) otherwise null),
    #"Filtered Rows" = Table.SelectRows(#"Added Custom", each ([Custom] = true)),
    #"Removed Columns" = Table.RemoveColumns(#"Filtered Rows",{"Custom"})
in
    #"Removed Columns"
Output
