What is XLSB file?

Documents in the XLSB format are binary files of a spreadsheet , generated by the Microsoft Excel 2007 program or newer. XLSB files contain data of a spreadsheet, which is a collection of cells based on the structure of columns and lines. The cells may contain text, images, charts, macros or formulas.

Creation of XLSB format

XLSB is a new format introduced along with Microsoft Excel 2007, which substitutes the previous, less efficient version – the XLS format. The new format is supposed to facilitate working with spreadsheets. It may be opened also by versions of Microsoft Excel older than 2007, howere certain problems may occur in such cases, like loss of certain functionalities.

XLSB vs XLSX

XLSX files are based on the XML structure and compressed using the ZIP compression method, and the XLSB files are uncompressed binary files. XLSB files contain data in a binary format, not XML, the processes of reading and storing takes much less time which is important especially in case of working with very large documents. Another advantage of the XLSB format is providing support for longer formulas, because it supports formulas longer than 8192 signs.

Note

XLSB files may contain macros which are scripts which will be executed on the device of person who will open the file. Therefore they are often used by Internet criminals. Special caution should be maintained while opening XLSB files received from unknown sources, so that our PC remain not infected with any viruses.
