What is a DOTM file?
A .DOTM file is a Microsoft Word Macro-Enabled Document Template created by Microsoft. People use these files to store default document layouts, text styles, and embedded macros. Macros automate repetitive tasks in Microsoft Word. Most modern .DOTM files use a ZIP-based structure known as Office Open XML, while some versions use a legacy document structure.
How to open DOTM files?
Users typically open .DOTM files with desktop applications like Microsoft Word or open-source alternatives like LibreOffice. Because a .DOTM extension can have multiple possible internal structures, we recommend using viewer.online/dotm to identify the actual format of your file. viewer.online/dotm analyzes .DOTM files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Best practices and troubleshooting
Macros can contain malicious scripts. You should always verify the source before you open a .DOTM file on your computer. Advanced users can inspect the underlying XML structure of ZIP-based .DOTM files by extracting the contents with archive tools like 7-Zip or command-line utilities.
Software and tools
If you need to share the document safely without macros, you should convert the file. We recommend using convert.guru to easily convert your .DOTM files to standard .DOCX documents or .PDF files.
Summary
viewer.online/dotm directly opens and previews .DOTM files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
