My app is a directory of businesses.A businesses fills out a google form with their information which gets sent the master sheet.
After this,I have to fill in additional columns, such as tags, roles, passwords, avatars, etc.
I would like for this to automatically populate once a new row is added.
Sure @Jen_NYCP, I do this all the time using GSheet ARRAYFORMULA.
ARRAYFORMULA is used when you need to place a formula in the first cell os a column and what that formula to be repeated in every cell below.
For example, if I need the content from every new cell in column B to be βNewβ, I can use something like that on the B2 cell (assuming that B1 is the header):
This will check if A2 to the last created A cell has any content, if its blank, nothing happens but if has anything, the value in B will be New for each valid row.
You can add the formulas in the header as @ThinhDinh suggested or in the first content row if you already have the content for it (I use this second option but both will work just fine).
BTW, amazing tutorial @ThinhDinh, I really wanted something like that when I was starting (and struggling) to use ARRAYFORMULA!
