Copy Monster Stat Block and create monster character sheet?

I remember being able to copy a monster stat block from my favorite website like PFSRD or maybe it was a d20 site for 3.5 D&D and then copy that into a character sheet here and viola, it populated a working monster sheet to which I could add a token. Somewhere along the line this has either stopped working, or I have forgotten how to do it, or possibly I dreamed the whole thing. Specifically for Pathfinder, 3.5 E D&D and 2e D&D, is there a way to do this and if so, can someone guide me to the guide? Thank you in advance.

AFAIK, the PF Community sheet was the only sheet of those mentioned that has a built-in parser similar to what you are looking for.  It allows for HeroLab imports on-sheet, but you would need the Pathfinder Companion Script (API mod) to import a properly formatted, raw text statblock from the PFSRD. I believe there are links to instructions in the mod's description.  Some parts of the mod may no longer function(last updated years ago...), but I believe the import option may still function.  YMMV

I will check into it, thanks. Back then I had no idea about scripts or API or anything like that. I swear you could just grab the monster sheet from the website and feed it right in (to the bio I think?) and, viola, working character sheet. I wish something existed like that for other game editions as well. I have a friend who runs 2e D&D almost exclusively, but struggles with making character sheets and if one could go to the Fandom website and pull stats and feed them into a sheet, his life would improve.
