How can I replace text in a DOCX file?

[sm-a]

I am new to Qt and hope I get an answer.
How can I replace text in a DOCX file? What library do I need. Best would be free (library). If possible give me an example to see how the library works.

Thank you for help.

There is nothing Qt for this. You won't get a suggestion for a library if you don't say say what programming language you are using. C++, Python?

If your application is running on a machine with Microsoft Word installed then you can automate it with ActiveQt.

Depending on the the complexity of the task you could unzip the DOCX file, modify the word/document.xml file it contains, and then zip up the result.

Unless you have other reasons to use Qt for this, I would consider using .NET. The library support for something like this should be much better there.

I use C++ as programming language. The application must be platform independent.

The solution for me is to write a .NET CORE application with the "DocumentFormat.OpenXml" library which is platform independent. Then I simply run this application under each platform to replace text.

Thanks for your help.

As you please, but doesn't running a .NET CORE application on each target platform require quite some installation/dependencies?

[sm-a]

Yes @JonB, it requires depencencies but this is not a problem. I will install this automaticly after users choice.

You can find them under:
LTS RELEASE
https://dotnet.microsoft.com/download/dotnet-core/3.1

Current release
https://dotnet.microsoft.com/download/dotnet/5.0

Note: .net CORE works with Linux, macOS und Windows.
