xltm

Xltm is a file format used by Microsoft Excel to store template files. It is an XML-based format that was introduced with Microsoft Office 2007 to replace the older binary file format used in previous versions of Excel. The "xltm" extension stands for "Excel Macro-Enabled Template," indicating that the file can contain macros, which are small programs that automate tasks within Excel.

Xltm files are typically used to create new workbooks with a predefined structure, formatting, and functionality. They can include formulas, data, and macros that are automatically applied when a new workbook is created from the template. This makes xltm files useful for standardizing reports, data entry forms, and other types of documents that require consistent formatting and functionality.

To open and edit xltm files, users need to have Microsoft Excel installed on their computer. When an xltm file is opened, Excel prompts the user to enable macros, as these files can contain potentially harmful code. Once macros are enabled, the user can edit the template as needed and save it in the xltm format or convert it to other formats such as xlsx (Excel Workbook) or xlsm (Excel Macro-Enabled Workbook).

Xltm files are stored in the same way as other Excel files, typically in the user's Documents folder or a designated folder for templates. They can be shared with others via email, cloud storage services, or other file-sharing methods. When sharing xltm files, it is important to ensure that the recipient has the necessary permissions and software to open and use the template.
