Convert QDF to XLS

qdf to xls conversion seems to mainly represent a transfer of data from Quicken financial format (.qdf) to Excel spreadsheet, often used for reporting purposes or to just work with the data in Excel. A typical .qdf file is basically standard XML file, BUT it has different header. If you know a thing or two about XML files, you just have to replace the header with a standard  line just before the tag. After that, you can rename the suffix from qdf to xml and import it to Excel like usual and save it as .xls or even .xlsx file once the data are supported.
