How to unzip xsd:Base64 Binary response to zip excel file.

Hi,
    We have a web service which is generating a report  as "From Date" to "To Date". User Need to specify those "From Date" and "To Date ".  When we are executing using SOAP UI the response came in (XSD: Binary X64 : Format with zip) like :

UEsDBBQACAAIALSVtDwAAAAAAAAAAAAAAAANAAAARzpcYWlzcF8yLmNzdrTdTauwS3qe53l+RdPjGOrj/qi3M1JIBho4CKSQsWI3jomsBsshfz+PIIYQvHctij7wQEaDsze717XQKo.

Is there any way we can unzip those binary responses  to zip format.


Thanks.
Jayanta
