Questions tagged [xssf]

XSSF provides Java APIs to read / write Microsoft Excel 2007 (OOXML format .xlsx) files. This tag should be used for questions about accessing Excel 2007 files from Java applications. XSSF is managed under the Apache POI Project. Other tag to consider: [tag:apache-poi]

HSSF is the POI Project's pure Java implementation of the Excel '97(-2007) file format. XSSF is the POI Project's pure Java implementation of the Excel 2007 OOXML (.xlsx) file format.
