EasyXLS

Convert XLS to XLSB

Concept

EasyXLS™ library allows you to convert Excel XLS file format to Excel XLSB file format.

EasyXLS can be successfully used inclusively to convert large Excel files having big volume of data with fast converting time.

EasyXLS permits you to convert Excel files without Excel installed, without Interop or any other additional software installed.

The conversion is made in two steps. First, the XLS file is imported and after that, the data is exported to XLSB file. Once the XLS was loaded in memory, optionally, the user can process data, add more features (like formulas, cell formatting, comments, hyperlinks, images, data validations, page setup, charts, and so on) and save the file back in XLSB Excel file format.
