The request names openpyxl, a Python library for reading and writing Excel files, but none of the candidate sources describe openpyxl or its type stubs (types-openpyxl). The closest match is the general-purpose Python type checkers and static typing tools (mypy, Pyrefly, ty) which could be used to type-check code that uses openpyxl, but none of them provides openpyxl stubs themselves. Since the sources do not show an openpyxl product, I cannot confidently recommend a product for it.
A question back: Do you want a type checker to use with openpyxl, or help installing and using the types-openpyxl stub package itself? The candidate sources do not describe openpyxl or its stubs directly.
