Numbers automatically detects valid web addresses (URLs) and email addresses and styles them (for example, with an underline or different color) to indicate that they’re active links. Phone numbers aren’t formatted as links by default, but you can turn on automatic formatting for phone numbers. You can also turn off automatic link formatting for URLs and email addresses.
To change whether or not Numbers formats website URLs, email addresses, and phone numbers as active links, you can update the settings for automatic formatting.
Go to the Numbers app
on your iPad.
Open a spreadsheet, then tap
at the top of the screen.
Tap Settings, tap Auto-Correction, then do any of the following:
If you don’t want links to show formatting but you still want them to be active, turn on Detect Web & Email Links or Detect Phone Links and turn off Apply Link Style.
The setting applies to new text that you enter in all Numbers spreadsheets. Existing links aren’t affected by the change.
