HELP: Adding Leading Zeros in Power Query

Hello

How do I add "0" to a column that has 5 digits, the columns should have 6 digits, but due to an error it was loaded without the leading zero.

 

Could you explain me the process because I am new in power query, would I have to generate a new column? or modify the one I have?

Hi @lottie2404 ,

 

I guess this column is automatically converted to an whole number type.

You can add a step to fix it by reconverting it to text type.

= Table.TransformColumns(#"Changed Type",{"Column1",each if Text.Length(Text.From(_))<6 then "0"&Text.From(_) else Text.From(_)})

Of course, if the column is of the correct type in the Source step you can unconvert it in the second step.

You can create a custom column (first make sure the column is changed to type text) using:

 

=Table.AddColumns(PriorStepOrTableName, {{"Padded", each Text.PadStart([NumberColumnName], "0", 1), type text}})
