  • Values, formulas, and formatting carry over into the modern Open XML template package.

Frequently asked questions

Does the template behave the same after converting XLT to XLTX?
Yes. Both are templates, so opening either creates a new workbook pre-filled with the template's formatting, formulas, and data while the original stays untouched.
Why convert XLT to XLTX?
XLT is the legacy binary template format; XLTX is the modern Open XML equivalent introduced with Excel 2007, so you keep the template role while moving to today's standard format supported by LibreOffice Calc and Google Sheets.
Are macros kept in the XLTX?
No. XLTX cannot contain VBA macros - that requires the XLTM format - so any macros in the XLT are not carried over.
What is preserved in the conversion?
The template's cell content, formulas, and formatting are preserved; only the container format is modernized and macros are excluded.
