Hello macropod. You mean to add a document here? But i do not know how to do it.

But to give a more pratical example, my objective is to generate QR codes.
So let's say i write 1234 in a cell.
I append the 1234 to this html string:https://api.qrserver.com/v1/create-q...&data=wxy.com/
I get this link https://api.qrserver.com/v1/create-q...a=wxy.com/1234
Which is the QR code to the desired site:

This way each time i change the number in the cell the QR code would update in document.
