This tutorial will show you how we can deal with empty or blank cell in excel file using Apache POI. We cannot handle blank or empty cell if we use cell iterator, so we have to get the maximum cell index for the row and iterate through index to deal with empty cell.
The Apache POI is to create and maintain Java APIs for manipulating various file formats based upon the Office Open XML standards (OOXML) and Microsoft’s OLE 2 Compound Document format (OLE2). You can read and write MS Excel files using Java. In addition, you can read and write MS Word and MS PowerPoint files using Java. Apache POI is the Java Excel solution (for Excel 97-2008).
