I am absolutely biased towards meta-sexp:

"A META parser generator using LL(1) grammars with s-expressions."

https://github.com/vy/meta-sexp

It seems dirt simple to use, at least to me and the performance has been acceptable.

Esrap is another packrat parser for CL:

I had to parse some semi-structured text and wrote Esrap for that. Its
primary limitations are lacking support for parsing from streams (it
wants a string) and very little documentation.
