DownloadJETT is a Java 5.0 API that reads an Excel spreadsheet as a template, takes your data, and creates a new Excel spreadsheet that contains your data, formatted as in the template. It works with .xls and .xlsx template spreadsheets.
Features
- Supports transformation of Excel 97-2003 (.xls) and Excel 2007+ (.xlsx) template spreadsheets.
- Integration with Apache Commons JEXL allows easy creation and evaluation of Expressions.
- Integration with SourceForge's jAgg project to extend JEXL with Aggregate Expressions.
- Built on the Apache POI library to manipulate Excel spreadsheets.
- Built-in Tag Library allows XML-like tags to allow programming-like constructs such as "ForEach" and "If".
- Looping Tags support "copy down" and "copy right" behavior.
- Custom Tag Libraries may be coded and supplied for execution.
- The CellListener interface allows custom processing of Cells.
- Merged cell regions, row heights, and column widths are respected.
- Like Apache POI, existing Excel features are kept intact, like Charts and Macros.
- Template Sheets may be cloned and processed in a loop.
- Multiple Collections may be implicitly processed in a loop.
- Adjacent, or side-by-side, display of Collections is supported.
- Rich Text Strings formatting is respected, even in Cells with Expressions.
- POI Objects are exposed, representing the Cell, Sheet, and Workbook objects.
- Excel formula generation support.
- JDBC execution of queries directly from the template spreadsheet.

We made extensive research and found this library as the best option to generate Excel spreadsheets from complicated templates. Really awesome!
-
It's much more powerful and flexible than jXLS.
-
A fairly decent library. Great Job Randy!
-
Excellent library. We use it with hugely complex templates with tens of sheet, Excel 2003 compatibility, and tortured styling, and it holds the load, and is even fast ! Jett has limits, that are always connected to the underlying Apache POI API, but it is THE product if you want simple enough reports for no cost and a little dev time.

Very nice idea! I'm a jxls user, but your api looks more flexible. unfortunatly i can't yet figure out how to use jett because i massly use SQL Execution in the Template so to write everything i need directly in Excel. I look forward to see how tris feature Will be implemented, Will it?
