Libraries for converting PDF to HTML for .Net

Question

HTML

I welcome everyone!
I ran into a problem: you need to pull out a lot of pdf-files with tables from a certain site and extract certain information from them.
Previously, in such cases, I used the Apache PDFBox for .Net library, it can convert pdf to html, which can already be parsed with regexps and pull out the necessary information from there.
However, this time it was not so easy to do, either the pdfs are too good, or something else, but the html code from them turns out to be very strange, in some cases it is almost impossible to parse it.
Do you know of equivalents to PDFBox that you can try using in .NET for such a task?
