Detect dates, contacts and more in documents on Mac

Many apps automatically detect data (such as dates, locations or phone numbers) that can be used in other apps, such as Calendar or Contacts; some apps may even suggest new events or contacts based on the data. For some apps, you can turn data detection on or off.

In an app on your Mac, open a document, then choose Edit > Substitutions > Data Detectors (a tick shows it’s on).
Move the pointer over a phone number, email address, street address, date or time anywhere in the text.
Click the arrow in the box that outlines the data to get more information about it (show an address on the map, for example). Control-click the arrow for more options.
