convert xslx files to csv format
xlsx files are zip archives where spreadsheet data is stored. In order to process a file, various bits inside the archive need to be located. This utility uses the Expat SAX parser to collect the strings into a simple dictionary, keyed by their relative position in the XML file. This makes it possible to process files of any size.
