This step is supported by the following backends:

Options reference

if: This is where you can specify a condition or a group of conditions. Please see the filter step documentation or more dtails on how conditions work.
then: here you can specify the value of the column if the if condition is evaluated to true. This parameter only supports a string, that will be interpreted as a formula (please see formula step documentation for more details on how a formula works). If you want it to be interpreted strictly as a string and not a formula, you must escape the string with quotes (e.g. “this is a text”).
else/elseif: here you can specify the value of the column if the if condition is evaluated to false. If else is selected, you need to specify a string that interpreted as a formula (please see formula step documentation for more details on how a formula works). If elseif is specified, you can nest another if...then...else block here.
