XLSX file format information

Full NameMicrosoft Excel Spreadsheet
Mime Typeapplication/vnd.openxmlformats-officedocument.spreadsheetml.sheet

XLSX files have been around since the mid-2000's and are one of the most popular spreadsheet file formats available. It was created by Microsoft as a modern update to the existing Excel XLS file format, with the intention of making future improvements to the format easier to implement than the original XLS format.

Contained within an XLSX file is the spreadsheet data stored within XML files. The XLSX file itself is simply a compressed ZIP container, meaning the format allows for all the Excel assets, such as spreadsheet data, images, and charts, to be stored separately within a single file structure.

As well as being the native format used by Microsoft's Excel application, XLSX files can also be processed by other spreadsheet applications, and third-party conversion tools can easily interface with the XLSX file format.
