I have two different columns with emails and I'd like to display all the emails in a separate column in the spreadsheet. Both the columns can be extended further so I can't select all cells statically. I tried doing ={(J2:J); (I2:I)} but it doesn't work.

You can try =flatten(I2:J)

The function is not officially documented, it litteraly flatten values in an array into a single column.

  • i ended up using filter to filter out blank values
