How do I convert a .ods file to .xlsx properly?

I have a spreadsheet with lots of complex formulas, macros, and conditional formatting. It works great in libreoffice calc, but I have to send it to someone who uses excel. I tried saving it in an excel format, but none of my conditional formatting worked, and some of the formulas didn’t convert properly either.

I understand that the macros I might have to redo, although if there was a way to convert them, it would definitely make my life easier. Is there a tool or addon that can help me make this conversion?
