The DOCX file format is the native file format used by Microsoft Word. It was created in the mid-2000s as a successor format to the older DOC file format. The switch from DOC to DOCX allowed for a fresh start, re-building the format from the ground up to be more flexible and easier to extend in the future.
A DOCX is actually a ZIP container file format, with the actual word document data stored within it in the form of many separate XML documents. This separation into individual XML documents means the relevant document components can be grouped together.
The use of the ZIP format as a container wrapper allows the DOCX files to remain small in size compared to the older DOC format. Along with Microsoft Word, there are many other Word processing applications that can open and work with documents in the DOCX format.
DOCX files contain a sequence of unique bytes at the beginning of the file. This header section is usually followed by the main DOCX file section. Where the header block is present, our document repair tool will parse the header data to validate the file type and also provide additional metadata that describes key characteristics of the document uploaded.
Microsoft Office formats such as DOCX are actually compressed container formats using the ZIP format as the underlying container. The data for these documents is stored in XML format. With this knowledge, our DOCX tool parses these documents to ensure the underlying XML is correctly formatted.
