Convert XLT to XLTX

Understanding xlt and xltx file formats

XLT is a Microsoft Excel Template file format used in Excel 97-2003. It allows users to create reusable spreadsheet templates with predefined formatting, formulas, and layouts. The XLTX format is the successor, introduced with Excel 2007, based on the Office Open XML standard. XLTX files offer improved compatibility, reduced file size, and enhanced security compared to the older XLT format.

Why convert xlt to xltx?

Converting XLT to XLTX ensures better compatibility with modern versions of Excel, leverages the benefits of the XML-based format, and future-proofs your templates for ongoing use.

The most reliable way to convert XLT to XLTX is by using Microsoft Excel itself. Here’s how:

1. Open your XLT file in Microsoft Excel (2007 or later).
2. Go to File → Save As.
3. In the Save as type dropdown, select Excel Template (*.xltx).
4. Choose your destination folder and click Save.

Best software for xlt to xltx conversion
