in reply to Reducing the memory usage of Spreadsheet::ParseExcel

And a Patch is now available for Spreadsheet::XLSX to do the same thing! (oops, ParseAbort not implemented yet as of this post. Update: Now it is!). Update2: Don't celebrate too much. Due to the method of reading the data, it actually still reads an entire worksheet into memory.

Update: Bah, forget this...just hang on and wait for jmcnamara's Excel::Reader::XLSX.
