'''xlsread''' and '''xlswrite''' are mere wrappers for '''xlsopen-xls2oct-xlsclose-parsecell''' and '''xlsopen-oct2xls-xlsclose''' sequences, resp.

'''xlsfinfo''' can be used for finding out what worksheet names exist in the file. For OOXML files you either need MS-Excel 2007 for Windows (or later version) installed, and/or the input parameter REQINTF should be specified with a value of 'poi' (case-insensitive) and -obviously- the complete POI interface must have been installed. | '''xlsfinfo''' can be used for finding out what worksheet names exist in the file.

When not using the COM interface, specify a value of 'POI' for parameter REQINTF when accessing OOXML files in xlsread, xlswrite, xlsopen, xlsfinfo (and be sure the complete Apache POI interface is installed). If you haven't got ActiveX installed (i.e., not having MS-Excel under Windows) specifying 'POI' may not be needed as in such cases Apache POI is the next default interface. | When not using the COM interface, specify a value of 'POI' for parameter REQINTF when accessing OOXML files in xlsread, xlswrite, xlsopen, xlsfinfo (and be sure the complete Apache POI interface is installed).

When using JExcelAPI (JXL), after writing into a worksheet you MUST save the file – adding data to the same or another worksheet is no more possible after the first call to oct2xls(). This is a limitation of JExcelAPI. | When using JExcelAPI (JXL), after writing into a worksheet you MUST save the file – adding data to the same or another worksheet is no more possible after the first call to oct2xls().
