Advantage of Apache POI over jExcel API

Here are the Advantage of Apache POI over jExcel API. The following article will shown my valid reasons

After further research, I found that Apache POI is the way to go for following main reasons. There are some other reasons related to advanced features but let’s not go into that much detail.

  • Backing of Apache foundation.
  • JExcel doesn’t support xlsx format whereas POI supports both xls and xlsx formats.
  • Apache POI provides stream-based processing, that is suitable for large files and requires less memory.
  • Apache POI provides excellent support for working with Microsoft Excel documents and it’s able to handle both XLS and XLSX formats of spreadsheets.

Some important points about Apache POI API are:

    • Apache POI contains HSSF implementation for Excel ’97(-2007) file format i.e XLS.
    • Apache POI XSSF implementation should be used for Excel 2007 OOXML (.xlsx) file format.
    • Apache POI HSSF and XSSF API provides mechanisms to read, write or modify excel spreadsheets.
    • Apache POI also provides SXSSF API that is an extension of XSSF to work with very large excel sheets.
    • SXSSF API requires less memory and is suitable when working with very large spreadsheets and heap memory is limited.

There are two models to choose from – event model and user model. Event model requires less memory because the excel file is read in tokens and requires processing them. User model is more object oriented and easy to use and we will use this in our examples.
Apache POI provides excellent support for additional excel features such as working with Formulas, creating cell styles by filling colors and borders, fonts, headers and footers, data validations, images, hyperlinks etc.
