A function that can subtract multiple values from another cell with multiple values.

Luis Salguero

In a sheet, there are the following:

The A field is a multi-select drop list column type. For example, the A@row cell has the values: 

'Apple Lime Orange Pear'

The B field is a multi-select drop list column type. For example, the B@row cell has the values:

'Apple Carrot'

The C field is a multi-select drop list column type with a formula that the result would be:

'Lime Orange Pear'

Which are the values in A not present in B.

The D field is a multi-select drop list column type with a formula that shows the value:

'Carrot'

Which is the value in B not present in A.

There isn't a direct function that can subtract multiple values from another cell with multiple values in Smartsheet.

However, if your B column only ever has a single value, we could use the SUBSTITUTE Function to subtract that single value from A:

=SUBSTITUTE(A@row, B@row, "")

But this won't work for subtracting A from B or if the B column has multiple values (see the orange cells where it's incorrect):
