I've created a spreadsheets consist of multiple complex dates & strings.
When I use concatenate, the date become numbers
=CONCATENATE('2021'!A2:'2021'!F61)
The results is like
44519in44471out44472Guest1in44475out44476SGuest2
How can I produce the result like this in one cell
November 2021
in 6/11 out 10/11 Guest 1
in 26/11 out 28/11 Guest 2
December 2021
in 29/12 out 31/12 Guest 3
I just need the copy & paste cell features, but I can't find any.
