What is XLT file format?

XLT stands for Excel Template. This file format is used to store spreadsheet templates that can be used over and over again to quickly create documents. With this format, users can save time by simply creating the template once and then using it whenever needed. XLT files contain standard cells and formatting, including data validation and worksheet protection settings, as well as any graphics, formulas, macros, and other customizations. XLT documents are created using Microsoft Excel and can be opened using most versions of Excel, including Excel 2011 for Mac.
