I would like to add some code into my Google Sheet. When I enter a number a url should be created

Question

It's simple but I am new to Google Sheets.

I enter a number in a field in a row. See img below.

When the number is entered I want it to turn into a hyperlink so it clickible.

Web Address example....http://idx.domain.com/details.asp?mls=77777777&aid=BB333833 Everything remains same. all thing that changes is the 77777777 (A2, A3, A4)

Answer 1

You can use onEdit() trigger. Set up an if statement, so that if the first column is edited change it's value to

"=http://idx.domain.com/details.asp?mls=" + your cell value + "&aid=BB333833"
