An XLX file is a file format used by Microsoft Excel to save and store Excel templates. Excel templates are pre-designed spreadsheets that are used to perform specific tasks. These templates are created by users or by Microsoft and contain predefined formulas, formatting, and layouts. An XLX file contains all of the information needed to create a new spreadsheet, including formatting, data, and formulas.

An XLX file is similar to an Excel workbook, but there are several differences. The main difference is that an XLX file contains a template, while an Excel workbook contains data. When you open an XLX file, Excel creates a new workbook based on the template. The new workbook contains the same formatting and formulas as the template, but it does not contain any data.

Another difference between an XLX file and an Excel workbook is that an XLX file cannot be edited directly. If you want to edit the template, you must open the file in Excel and make the changes you want. Once you have made the changes, you can save the template as a new XLX file.

XLX files are useful for businesses that have standard worksheets that are used repeatedly. A company might create an XLX file with a set of formulas to calculate a particular type of business analysis. Then, each time that type of analysis is required, an XLX file can be created from the template with minimal effort. This saves time and ensures consistent reporting.

In addition to XLX files, Excel also uses other file formats. XLSX is the most common file format used by Excel. It is used for saving Excel workbooks that contain data. XLSM is used for saving workbooks that contain macros. XLSB is used for saving workbooks that contain a large amount of data.

Overall, an XLX file is a file format used by Microsoft Excel to save and store templates. These templates can be used to create new spreadsheets quickly and easily. XLX files are useful for businesses that have standard worksheets that are used repeatedly. Excel also uses other file formats, including XLSX, XLSM, and XLSB, for saving workbooks with data, macros, or large amounts of data.
