Create XLSX Files

XLSX is the default file extension used to represent the documents natively generated by Microsoft Office Excel 2007 or later. Unlike the XLS format it resembles, XLSX is based on XML structure and uses ZIP compression.

Frequently referred to as spreadsheets, XLSX files contain cells arranged as rows and columns which feature graphs, math function, formatting settings and styles.

When users want to create XLSX files, they will need to find a specialized software application that allows them to save their documents as XLSX.

Another method of creating this type of files is to convert files of other formats to XLSX using specialized utilities.
