What is a DOCM file?
A .DOCM file is primarily a Microsoft Word Macro-enabled Document. It is a document file developed by Microsoft for use with Microsoft Word. Most .DOCM files use a ZIP compressed structure that holds XML files, text, and images. The key feature of a .DOCM file is that it contains embedded macros. Macros are scripts written in Visual Basic for Applications (VBA) that automate tasks within the document.
How to open DOCM files?
The primary software used to open and edit .DOCM files is Microsoft Word. You can also open these files using free office suites like LibreOffice Writer or Apache OpenOffice, but complex macros might not function correctly in these alternative programs. Because older versions of Word use different internal structures, a small percentage of .DOCM files might be based on the legacy DOC format instead of the modern ZIP structure.
Best practices and troubleshooting
Because .DOCM files contain executable code, they can be a security risk. You should only enable macros if you trust the sender. If you want to safely inspect the contents of a macro document without running malicious scripts, viewer.online/docm analyzes .DOCM files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. If the .DOCM extension has multiple possible meanings, viewer.online/docm helps you identify the actual format of your file.
Software and tools
If you need to share the document with users who do not need the macros, it is best to convert it to a safer format. We recommend using convert.guru to easily convert your .DOCM files into .DOCX, .PDF, or .ODT formats.
Summary
viewer.online/docm directly opens and previews .DOCM files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
