XLSB File Support

Aug 7, 2013 at 2:51 PM
I have a client that converted their XLSX files to XLSB for speed, and now I can't use my epplus application to view and extract data from those files. Any idea how to make this work?

EPPlus does not support the binary format. We are currently focusing on implementing new features in the .xlsx format.

This post is fairly old now, wondering if the XLSB Format supported in the latest version? If so, how is it implemented?

Thank you.
