Not in a single cell, but you can set up multiple columns like (Email 1, Email 2, Email 3). This will give you a single column option (Email) that you can use for per user data.
OK @Jeff_Hager, thank’s, il will help me.
How many columns like (Email 1, Email 2…) can we add ? Is there a limit ?
Yes, there’s a limit. Sheets can only have 18,278 columns. Not sure if glide would like that, but theoretically it should work.
