We’re thinking about revising all of our Excel files to use the Excel xlsb binary format. Are there any features in the Aspose.Cells product set that would not be supported with xlsb? We use macros, etc. in our Excel files.
Well, Aspose.Cells does support all the native file formats of MS Excel (2003-2007/2010 and 2013) inlcluding XLSB file format, you may create, manipulate or render XLSB file format. Regarding Macros, Aspose.Cells does support to retain macros (in the template file) and re-save the file with it without any loss but it does not support to create, manipulate or execute vba codes/ macros in the Excel spreadsheets.
Please try our latest version/fix(e.g v8.2.2.x), if you find any issue, let us know with all the details, sample code and template files, we will check it soon.
