I suggest looking at some AI tools. Three that I'm aware of are
- ALEX
- Sovren
- Resume Mirror
I think all the products handle Word, txt, and pdf along with a bunch of other document types. Although I've never used it, I've heard unfavorable things about Resume Mirror's accuracy and customer support. I'm a contract recruiter and have used both Sovren's and Hireability's parsers in different ATS's. From my view I thought Hireability did a better job, with Sovren it seemed like I was always fixing errors. And when there was a goof with Hire's I gave it to my ATS vendor and it seemed like it was fixed pretty quickly. Good luck.
