Hi Anchal,
Agree with Dan Gage.
But your business requirement mandates that you need to have address line1 and address line2 concatenated before address cleansing, I would recommend that you concatenate them as part of the data loader functionality and map to Address Line1.
Let me know if you need more information.
Thanks
