Build 3.5.0.84 adds support for importing Excel XLSB files.

XLSB files were introduced along with XLSX/XLSM/XLST/XLSA files a few years ago. XLSB files are binary files and have nothing to do with XLS files.

xlsgen imports many of the features in XLSX files. Among them :

- cells
- formatting
- formulas
- charts
- text boxes and vector shapes
- pictures
- defined names
- conditional formattings
- page setup
- VBA macros


To use this feature, just pass a XLSB file (or XLSB memory buffer) to the Open() method.
