How to convert XLT to XLSX
- Add your .XLT file - drop it in the box above or click to browse.
- Convert it to .XLSX in a few seconds.
- Download your new .XLSX file.
What to expect
- Values, formulas, and formatting carry over; VBA macros do not, because XLSX cannot store them.
- The result is a normal editable workbook, not a template that spawns new files.
- XLSX is a ZIP-based package and is usually more compact than the legacy binary format.
Frequently asked questions
Is any data lost moving from XLT to XLSX?
Ordinary content - values, formulas, and formatting - is preserved. The main thing that cannot cross over is VBA macros, since plain XLSX cannot store them.
Why convert XLT to XLSX?
XLT is a legacy binary template; XLSX is the modern Open XML workbook used since Excel 2007, giving you an editable file in today's standard format that Google Sheets, LibreOffice Calc, and Excel for the web all handle.
What happens to macros in the template?
They are dropped. XLSX cannot contain macros - a macro-enabled workbook would need the XLSM format - so any VBA code in the XLT is not carried into the XLSX.
Will the XLSX be smaller?
Often, yes. XLSX is a ZIP-compressed XML package, so it is typically more compact than the older binary format for the same content.
