I recently spent several days improving the OCaml FreeTDS C bindings for work, and I thought it might be useful to share the problems I ran into and how to solve them.

I recently finished a basic XLSX reader for OCaml and I thought it would be a good time to summarize what's necessary to make a library like this, since the documentation is complicated and sometimes hard to find.
If you're planning to read XLSX files, you probably want to …
