What is XLTM file format?
XLTM is an XML-based file format used by Microsoft Excel to save spreadsheet data. It is an alternative to the XLSX file format, which is the current default format for new spreadsheets created in Excel. XLTM files are especially useful for workbooks that contain macros or other automation code, as they allow the code to be saved along with the data. They provide added security as they can be password protected and also allow for digital signing. XLTM files are not supported by all spreadsheet applications, so it is important to make sure that the file is opened with the program that created it.
