XLSX

Office Open XML Worksheet Sheet

The XLSX format is a file format used by Microsoft Excel for storing spreadsheet data. It is an updated version of the XLS format and is based on the Office Open XML (OOXML) standard. XLSX files are designed to be more efficient and compact compared to their predecessor. They can contain multiple sheets, each with its own set of rows and columns, and support various data types, formulas, and functions. XLSX files also offer improved compatibility with other software applications and platforms, making it easier to share and collaborate on spreadsheet data. Additionally, XLSX files can be customized with formatting options such as fonts, colors, and borders to enhance the visual presentation of the data. They can be opened and edited in Microsoft Excel or other spreadsheet software that supports the XLSX format.
