MS completely redesigned their binary formats a few years ago. You're right about the current format, but the earlier one was completely undecipherable. Even the current XML has quirks in it to be compatible with the older format.

It was reversible enough to write the Apache POI library. I maintain code that uses the HSSF streaming API portion of the library, which mainly gives you low-level access to the structures in XLS files. The OO.org folks made some very nice documentation: http://www.openoffice.org/sc/excelfileformat.pdf
