What Is an XLSX File?
XLSX is an Open XML Spreadsheet format developed by Microsoft for its industry-leading spreadsheet software, Microsoft Excel. It is the newer version of XLS and the default file format for saving documents in Microsoft Excel 2007 and later. So what is an XLSX file? In simple words, an XLSX file is an Excel file for creating spreadsheets.
An XLSX file uses the filename extension .xlsx. It stores data in worksheets or workbooks. A workbook refers to an entire file and can contain multiple worksheets. Every XLSX file and its worksheet is made up of rectangle cells formed by intersections of rows and columns.
XLSX files are believed as the optimal file type for organizing and managing tables, text, shapes, and other data information. Specifically, you can apply formulas in XLSX files to calculate, filter, present large amounts of data, etc. They can contain charts, mathematical functions, styles, and formatting if needed.
XLS vs XLSX
Although both XLSX and XLS are the native file formats of Microsoft Excel for producing spreadsheets, they have many differences such as the file extensions .xlsx and .xls. Some other differences between XLS and XLSX are as follows.
XLSX, the Open XML Format uses zip compression technology to store documents, and thus XLSX files are smaller than XLS files.
As XLS is the default file format of the older Microsoft Excel versions (Excel 97 to Excel 2003), it has higher compatibility than XLSX. That is to say, XLS files are accessible by any Microsoft Excel version while XLSX files are only readable by Excel 2007 and later.
Support Macros or Not
XLS files support Macros, a kind of program that users can write to automate those repeated tasks such as data comparison. However, XLSX files do not support Macros.
Macros benefits users while threatening the security of computers as well. Why? Some viruses written in the same macro language will run when you open an XLS file. Therefore, XLSX files are relatively more secure.
Files in the XLSX Open XML format support many advanced features of Microsoft Excel, such as AutoSave and Accessibility Checker.
