Excel tools plug in for XLSB files

Hello. I am having a trouble while using this plug-in. i am trying to get data from a cell in an excel file but the file is in the xlsb format and the plug in gives me the following error : Expression evaluation error at function 'readexcelsheetpaging': com.github.pjfanning.xlsx.exceptions.OpenException: org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 1; Invalid byte 1 of 1-byte UTF-8 sequence.

is there anyway to use this plugin for these files?

Or is there any work-around to get this same functionality? This is a step in my process model where the user has submitted the excel document.
