Easily convert your XLSX files to RB format in the Ebook category with ConvertOnline's efficient tool.
The XLSX file format is a spreadsheet file format created by Microsoft Excel, which is part of the Microsoft Office suite. It is based on the Open XML format and is widely used for storing and managing data in tabular form, allowing users to perform calculations, create charts, and analyze information efficiently.
The 'rb' file format is primarily associated with Ruby scripts that are executed in a binary format. It allows for the execution of Ruby code that may include compiled extensions and optimizations, making it efficient for performance-sensitive applications.
