    Hi!

    The easiest way to do this is Generate Attributes with the replaceAll function.

    It takes three parameters: The name of the attribute to read (column_1), the regular expression to search for, and the replacement (the empty string "").
    A regular expression to find leading spaces, zeros and dashes would be this: ^[0 -]+
