Convert XLT to NMBTEMPLATE

Apple Numbers does not natively support the templates from Microsoft Excel (.xlt), which makes xlt to nmbtemplate conversion not that easy. Converting an XLT (Excel Template) file to an NMBTEMPLATE (Apple Numbers Template) file involves a few steps, as there's no direct software to perform this conversion.

How to convert Excel templates to Numbers template

1. Open the XLT file in Microsoft Excel, as XLT is an Excel Template file format. So, the first step is to open this file in Microsoft Excel.
2. Save the file in a common XLSX spreadsheet format. Click on File > Save As and choose Excel Workbook (*.xlsx file extension) from the drop-down menu.
3. Open the saved file in Apple's Numbers application.
4. Save the file as a Numbers Template. Go to File > Save as Template. This will save your file as an NMBTEMPLATE file.

Please note that this process might not perfectly preserve all formatting and features of the original Excel template, as Excel and Numbers differ in their capabilities and features. Unfortunately, no specific software can directly convert XLT files to NMBTEMPLATE files. However, the above method should work without any issues in most cases.
