What kind of programming language would be better/ easily to program
Idea: As user after login, upload file (for example Word document) -> program change text formatting in Word document (formatting like font, font size, text colour). Different users this formatting could be different defined. And there should be opportunity to set different formating to heading and different to normal text (like Styles in MS Word)
My first version was, that should use VisualBasic. Now heared that could use HTML is it true? Maybe there is another idea how to realise it?
What I have tried:
Started project in VisualBasic. Can upload document, add text.
Can't understand how to check specific text style like Heading, normal tex, or table for formatting
