Microsoft Office Binary File Format Validator 14.0

Office File Validation (OFV) is a security feature that was introduced in Microsoft Office 2010. Office File Validation verifies that a particular binary file complies with the application’s expectations. Office File Validation can help prevent unknown binary file format attacks against Microsoft Office 97-2003 file formats.

When you open Microsoft Office 97-2003 binary file (such as .doc) the file is compared to a binary schema. If the file fails this validation, you are notified that the document could be considered to be compromised.
