Description🔵 XLT is a file extension used by Microsoft Excel to denote template files created with the software. Like other Microsoft Excel files, XLT files are spreadsheet files that can contain data, formulas, charts, and other elements commonly used in financial or accounting analysis, data management, and project management.
Technical details🔵 XLT files are similar to XLS files, which are regular Excel files that can be opened and edited directly. The main difference between the two is that XLT files are intended to be used as templates, meaning that they can be customized and saved as XLS files, which can then be edited and manipulated directly. When an XLT file is opened in Excel, a new workbook is created based on the template. This workbook contains all the formulas and formatting specified in the template, as well as any pre-defined data or charts. Once the new workbook is created, the user can modify or add new data as needed, save the file as an XLS file, and use it for analysis or reporting purposes.
