What are the new file extensions in Office 2007?
Microsoft Office 2007 uses new XML-based file formats, which have new file type associations and extensions, as follows:
| Application | Office file type | Extension | Description |
| Word | Word 2007 XML document |
.docx |
New default Word 2007 file format |
| Word 2007 XML macro-enabled document | .docm |
Uses same basic Word 2007 XML document format, but can store VBA macro code | |
| Word 2007 XML template |
.dotx |
Default format and extension for Word document templates | |
| Word 2007 XML macro-enabled template | .dotm |
Format and extension for Word document templates that can support macro code. The templates do not need to contain macro code when created; that code can be embedded later. | |
| Excel | Excel 2007 XML workbook |
.xlsx |
Default Excel 2007 file format |
| Excel 2007 XML macro-enabled workbook | .xlsm |
Uses same basic Excel 2007 XML worksheet/workbook format, but can store VBA macro code | |
| Excel 2007 XML template |
.xltx |

| Excel 2007 XML macro-enabled template |
.xltm |
Format and extension for Excel worksheet templates that can
support macro code. Can contain a VBAProject part or Excel 4.0 macro
sheets (.xlm files in Excel 4.0). Workbooks created from
this template inherit the VBAProject part or Excel 4.0 macro sheets
that exist in the template.
|
|
| Excel 2007 binary workbook (BIFF12) | .xlsb |
Fast load-and-save file format for those who need the fastest way
possible to load a data file. Supports use of VBA projects, Excel 4.0
macro sheets, and all the new features in Excel
2007.
Note: This is not an XML-based file format, so it's not the best choice for accessing and manipulating content without the use of Excel 2007. |
|
| Excel 2007 XML macro-enabled add-in |
.xlam
|
A supplemental program designed to run additional code. Excel add-ins use the new XML file format to store data. Excel XML add-ins support the use of VBA projects and Excel 4.0 macro sheets. | |
