How can I avoid that a Calc cell with an @ is not formatted as an e-mail address?

I have a column of text that is syntactically email addresses. Some of them a formatted under
my control (font, size), but some are formatted in a way that I can’t change and as e-mail addresses.
I would like them all to be considered as text.

Hi - AutoCorrect +1

And to convert cells that already contains @:

  • Edit Find & Replace
  • Search for @
  • Replace with &
  • Other options, check Regular expressions
  • Replace All
