How to convert XLSX to XLTX
- Add your .XLSX file - drop it in the box above or click to browse.
- Convert it to .XLTX in a few seconds.
- Download your new .XLTX file.
What to expect
- Both formats share the Open XML family, so formulas, formatting, and data are preserved.
- The output behaves as a template: opening it starts a new workbook and leaves the template unchanged.
- Any VBA macros are not carried over, since XLTX cannot store macros.
Frequently asked questions
What is the difference between the XLSX and the resulting XLTX?
Both use the same modern Open XML format; XLTX is the template variant. Opening the XLTX creates a new workbook pre-filled with its content and formatting, leaving the template file untouched.
Why convert XLSX to XLTX?
To turn a finished workbook into a reusable template for invoices, reports, or forms you start from repeatedly.
Is any data lost going from XLSX to XLTX?
Because both are the same Open XML family, formatting, formulas, and data are preserved. The main change is behavioral: the file now acts as a template.
Can VBA macros be included?
No. XLTX cannot hold VBA macros; a macro-enabled template requires the XLTM format instead.
