Is there a way to convert docx to TextMeshPro's rich text?

Hi all,

I need to display my docx containing different size texts, different colors on Unity. When I read the docx as a text file, TextMeshPro shows it all in the same size and same color as expected. How can I read docx with all the formatting and display it on Unity with TextMeshPro's rich text feature?

EDIT: I just want to show the text in the format I did on Unity. So it should look like this on Unity:

Anyway to get this look on Unity by reading docx or rtf file?

 

I can also convert docx to rtf file, but the formatting of rtf file looks different than TextMeshPro's rich text.

I'll leave example files in case anyone wants to try it (docx and rtf)

I cannot update rtf file somehow, so I'll copy-paste it here:

Spoiler: .rtf file

I'm curious about this as well. Did you find an answer?
