How to insert a new row with data and formulas in Google Sheets

Pau Sanchez Updated by Pau Sanchez

Landbot is great at adding data to your Google Spreadsheet, but in some occassions, you might want to do some calculations based on the user inputs that you send to Google Spreadsheets.

Normally you would add more data by using "Insert a New Row", and is great but, you cannot use formulas at that row, or apply the same formula to the whole column.

However there is a way to do this: ARRAYFORMULA. We've been inspired by an article from that describes a method that will be very handy in Landbot.

In this example we will obtain the volume of a room (m3) based length, height and width (in cms):

  1. We set up the Columns of the Spreadsheet

  1. The goal is that volume always displays the result of the operation. The standard formula would be:

  1. As we want to be always the content no matter in which row is the formula should be change to:

  1. Here is where we want that the ARRAYFORMULA method is applied to all the column:

  1. But we want to apply directly from the first row, so we set up the condition and move the formula up, and set up a condition where we set up that if is the first row, the value of the cell will be "Volume":

  1. Now is the important bit to be used in Landbot. Here we add a condition, that specifies that if there is missing a value of Length, do not trigger the formula, so it won't add results when there is no Length value


  1. In Landbot now we can Set up the question for the inputs and Google Spreadsheet block to Insert a New Row, where we will add only the Length, Height and Width:
