Answer 2

Answer:

.xlsb

Explanation:

The Microsoft Excel Binary File format, with the . xlsb extension and referred to here as XLSB, was introduced in Microsoft Office 2007, at the same time as the XML-based formats of the Office Open XML (OOXML) family. Unlike that family of formats, XLSB is not an international standard.
