    Hi Anu,

    Since office 2007 Microsoft has changed the office file formats (including excel and Word). All the formats prior to office 2007 were without x e.g .xls and .doc. Before 2003 file format was a Binary Interchange File Format.

    Since office 2007, Microsoft adopted a new file format which was tightly derived from XML file format. This new file format is called Office Open XML format. As it is Xml based format,  they added an X (from Xml) to the file extension. Hence we have .xlsx and .docx.

    While doing Java interoperability, for the  Open office xml format Java developers created a new parser and corresponding Object model was named XSSF.

    Thanks

    Hi anu,
    I have mentioned the difference between HSSF and XSSF below.

    HSSF (Horrible SpreadSheet Format) – reads and writes Microsoft Excel (XLS) format files. It can read files written by Excel 97 onwards; this file format is known as the BIFF 8 format. As the Excel file format is complex and contains a number of tricky characteristics, some of the more advanced features cannot be read.

    XSSF (XML SpreadSheet Format) – reads and writes Office Open XML (XLSX) format files. Similar feature set to HSSF, but for Office Open XML files.
