Handling Microsoft Word file format

This page discusses various available options for working with Microsoft Word documents in your Qt application. Please also read the general considerations outlined on the Handling Document Formats page.

of completeness or correctness. In particular, use your own research and judgment when evaluating third-party libraries or tools!

One needs to distinguish between two different formats (this page deals with both of them):


Legacy "Word Document" format "Office Open XML Document" format
classification: binary XML-based
main filename extension: .doc .docx
main internet media type: application/vnd.ms-word application/vnd.openxmlformats-officedocument.wordprocessingml.document
default format of Word: until Word 2003 since Word 2007

Reading / Writing

Using Word itself

If you are exclusively targeting the Windows platform and Microsoft Word will be installed on all target machines, then you can use Qt’s ActiveX framework to access Word’s .doc and .docx processing functionality through OLE automation. For an introductory code example (and a way to list the API provided by Word's COM object), consult this how to (focuses on Microsoft Excel, but it works the same way for Word).

DLL file name COM object name platforms license
Microsoft Word  ? Word.Application Windows commercial

Using independent parser/writer libraries

API .doc .docx reading writing platforms license
wv C yes no yes no Win, Mac, Linux GPL [strong copyleft]

Using manual XML processing

Files using the XML-based (.docx) format could be processed using Qt's XML handling classes (see Handling Document Formats).

Using batch conversion tools

If all else fails, there is always the option of using an existing tool to automatically convert between Microsoft Word files and a more manageable format, and let your Qt application deal with that format instead. The conversion tool could be bundled with your application or specified as a prerequisite, and controlled via Doc:QProcess. Some possibilities are:


.doc to .docx to … to .doc … to .docx platforms
AbiWord .txt .rtf .html .dbk .odt .docx … .txt .rtf .html .dbk .odt … - .txt .rtf .html .dbk .odt .doc … Win, Mac, Linux, …
wvWare .txt .rtf .html .dbk … - - - Win, Mac, Linux, …

Notes:

AbiWord can be used like this for batch conversion:
abiword to=outputfile.rtf inputfile.doc
