Issue Details

I would like to read plain text from a Microsoft Word document in LabVIEW. Is this possible?

Solution

You can read text from a Microsoft Word document using the Microsoft ActiveX API. See Figure 3. for an overall reference. The basic process is as follows:
 
  1. Open a reference to the Microsoft Word application using the LabVIEW Automation Open function.
  2. Access the Documents object, a property of the newly created Application object.

  1. Invoke the Open method, and specify the path to the document you wish to open.
  2. Access the Content property of the Document object. This is a Range object comprising the entirety of the opened document.
  3. Access the Text property of the Content object. This returns a string containing the text of the Word document.
