Convert macro-enabled Excel templates (XLTM) to standard spreadsheet documents (XLSX) instantly. This tool is essential when you need to share templates safely with users who should not execute internal VBA scripts.

XLTM is a Microsoft Excel Macro-Enabled Template format designed to generate new spreadsheets with pre-configured VBA code and macros. XLSX, on the other hand, is the standard OpenXML spreadsheet format that does not support executable macros. When converting XLTM to XLSX, the conversion utility strips out the macro layer and macro-specific extensions while keeping your data, tables, and formatting entirely intact.

The conversion between XLTM and XLSX occurs without data loss regarding your layout, formulas, and visual formatting. However, remember that any embedded VBA macros will be permanently removed from the resulting XLSX file.

Tips

Ensure all critical macros are saved in a separate backup before converting if you still need the code.
Check that your formulas rely on standard Excel functions rather than custom VBA-based UDFs (User Defined Functions).
Verify that conditional formatting and charts render correctly in the final XLSX spreadsheet.

Common use cases

Sharing an enterprise budgeting template with external clients who block macro execution for security reasons.
Publishing clean, macro-free template files to a shared company repository or cloud drive.
Preparing legacy macro-templates for compatibility with third-party spreadsheet viewers that only read XLSX.
