Unable to send a Numbers doc.......(arrrggg)

Why would you want to change the extension? It is a Numbers file and that is the proper extension. If your recipients are expecting an Excel file or PDF, you will need to export to that format first (Share does this as part of its process). File/Export to...

Hopefully the Share feature will start working again when you reboot and you won't have to go through these extra steps.

"Numbers App puts ".numbers" as the extension on the created spreadsheet. It won't let me change it. (sheesh)"

Numbers adds the .numbers file extension to identify the file as a Numbers file.

What change do you want to make in that extension? Why?

Changing that extension to anything else does not change the file.

What are the recipients using to attempt opening the file?

With all this interlinked stuff, it is often hard to tell where the problem lies. Have you tried the old method of going into your email, creating a message, and attaching the document to it?

Where are you storing your Numbers documents? Sharing should work well if you have them in iCloud Drive.

Also, sometimes strange problems disappear if you simply restart your Mac.
