What is DOTX? Word Open XML Template Explained
DOTX is a Microsoft Word template file in the Office Open XML format, used to create new documents.

What is DOTX?
DOTX is the Microsoft Word template format introduced with Office 2007. It stores the layout, styles, formatting and boilerplate content used as a starting point for creating new documents.
Built on Office Open XML, a DOTX file uses the same ZIP-and-XML packaging as DOCX but is treated as a template: opening it normally creates a new document rather than editing the template itself. Unlike the older DOT or the macro-enabled DOTM, DOTX cannot store VBA macros.
How a DOTX Template Works
A DOTX is an Office Open XML package, structurally similar to a DOCX, but its content type marks it as a template so that opening it spawns a new document attached to the template rather than editing the template directly.[1] The package can carry styles, theme parts, page layout, building blocks, and boilerplate content that the derived document inherits.[3]
History and Standardization
DOTX arrived with Office 2007 as the XML successor to the legacy binary DOT template, built on the Ecma- and ISO-standardized Office Open XML format.[2] Microsoft separated templates into a macro-free DOTX and a macro-enabled DOTM, mirroring the DOCX/DOCM split, so that template files distributed widely could be treated as non-executable.[1]
DOTX vs DOT and DOTM
Unlike the older DOT, which used Word's compound-binary structure and could embed macros, DOTX is transparent ZIP-and-XML and explicitly cannot store VBA; macro-enabled templates must use DOTM.[3] Word's global Normal template historically shipped as Normal.dot and corresponds to this template role in document creation.[2]

| Role | Template[1] | Document | Template |
| Macros | No | No | Yes |
| Standardized by | ECMA / ISO[3] | ECMA / ISO | Microsoft |
| Open/proprietary | Open (vendor-led)[2] | Open (vendor-led) | Proprietary |
| Best for | Reusable templates | Editable documents | Legacy templates |
DOTX is the modern XML template counterpart to DOCX, replacing the older binary DOT template format.
Advantages & Disadvantages
Advantages
DOTX templates enforce uniform styles, fonts and layouts, helping teams produce documents with a consistent look.
Unlike DOT or DOTM, DOTX cannot contain VBA macros, reducing the security risk when sharing templates.
Opening a DOTX generates a fresh document while preserving the original template for repeated use.
Disadvantages
Templates needing automation must use the macro-enabled DOTM format, since DOTX deliberately excludes VBA code.
Full template behavior, including building blocks and styles, is best preserved within Microsoft Word.
Common Use Cases
DOTX is used to standardize the creation of repeated document types.

What is the difference between DOTX and DOCX?
DOCX is a regular Word document, while DOTX is a template. Opening a DOTX creates a new document based on it, leaving the template unchanged so it can be reused repeatedly.
What is the difference between DOT and DOTX?
DOT is the older binary Word template from before Office 2007, while DOTX is the modern Office Open XML template. DOTX also cannot store macros, whereas DOT could.
Can a DOTX file contain macros?
No. DOTX is macro-free by design. A Word template that needs embedded VBA macros must be saved in the macro-enabled DOTM format instead.
How do I create a DOTX file?
In Microsoft Word, design your layout and styles, then choose Save As and select Word Template (.dotx) as the file type. The document is stored as a reusable template.
