Create, read, write Word and PDF in Python
GemBox.Document is a .NET library that enables you to process Word files from any .NET application. But it's also a COM accessible library that you can use in Python as well. To use GemBox.Document in Python, you'll need to: The following example shows how you can read a template Word file from Python, edit its content (with Find and Replace, Mail Merge and Modify Bookmarks operations) and write it as an output file of PDF format. Not all members of GemBox.Document are accessible because of the COM limitations like unsupported static and overload methods. That is why you can use the However, if you need to use many GemBox.Document members from Python, a recommended approach is to create a .NET wrapper library instead. Your wrapper library should do all the work within and exposes a minimal set of classes and methods to the unmanaged code. This will enable you to take advantage of GemBox.Document's full capabilities, avoid any COM limitations, and improve performance by reducing the number of COM Callable Wrappers created at runtime.System Requirements
