Detecting paragraphs and font styles using spire.PDF!?

[A.S.]

Can spire.pdf detect paragraphs and font styles like bold, italic, superscript, subscript etc. and save it to a text file?
I have uploaded a pdf file(as input) and a txt file(as desired output)

Hi,

Thanks for your inquiry.
Sorry that our Spire.PDF can't achieve your need to detect paragraphs and font styles and write them to text file. If you have other questions, welcome to write back.

Sincerely,
Nina
