What is an XLTX file?

An XLTX file is a template created by Microsoft Excel, a spreadsheet application included in the Microsoft Office suite. It contains predefined settings and layout information used to create .XLSX files. XLTX files are used to create multiple spreadsheets with common formatting and properties.

Microsoft Excel includes a number of pre-created XLTX files that allow you to quickly create common documents, such as budget planners, calendars, and invoices, from predefined templates. You can also create custom templates from your own spreadsheets, allowing you to quickly create similar spreadsheets in the future.

XLTX files are saved using the Open XML file format Microsoft introduced in Microsoft Office 2007. They replaced .XLT files, which were stored in a binary format.

Excel is the most widely-used spreadsheet application in the world. It comes with every edition of the Microsoft Office suite and is used in home, academic, and business environments.

How do I open an XLTX file?

You can open XLTX files in Microsoft Excel (Windows, Mac, iOS, Android). To do so, select File → Open from the program's menu bar. After you do, you can either edit the template the XLTX file contains, or you can use the XLTX file to create a new spreadsheet.

Note that, in order to open XLTX files in Microsoft Excel 2003 and earlier versions, you must install the Microsoft Office Compatibility Pack. If you have not installed the compatibility pack, you will not be able to open your XLTX file in Excel 2003 and earlier versions.
