am I able to export and convert to excel?

Go to File > Export to… & choose Excel. Keep in mind that exporting/importing other formats such as Excel is a translation process. Features unsupported in the chosen format will be ignored. Your recipient will likely not see exactly what you do. If the recipient only needs to read the data, export the Numbers file to PDF to take a virtual picture. You could send both the Excel file & the PDF for clarity.

Numbers can export directly to the Microsoft Excel file format.

And can import Excel files.

Numbers does a pretty good job of opening most Excel spreadsheets, and exporting Numbers documents as .xlsx.

However, because of the differences between the two apps, formatting (and some formulas) may not transfer perfectly.

If you are collaborating frequently with Excel users, with documents sent back and forth, then the only thing fully compatible with Excel is ... Excel. Excel for the Mac is an excellent app and is available on the Mac App Store.

If you are only on the Mac, no mobile, then LibreOffice and other clones are also good choices for frequent collaboration with Excel users.
