The inequality (!=) operator returns true if its operands are not equal. It accepts operands of all data typesstrings, numbers, Booleans, and dates.

string != string
number != number
boolean != boolean
date != date
list != list

unequal(string, string)
unequal(number, number)
unequal(boolean, boolean)
unequal(date, date)
unequal(list, list)

Code language: JavaScript (javascript)

Good to know: Notion now allows for comparisons between different data types, and the inequality operator (!=) will act as a strict inequality operator. For example, "1" != 1 will return true

You can also use the function version, unequal().

1 != 2 /* Output: true */

1 != 1 /* Output: false */

unequal("Cat","Dog") /* Output: true */

"Cat".unequal("Dog") /* Output: true */

"1" != 2 /* Output: false */

2^3 != 10 /* Output: true */
Code language: JavaScript (javascript)

Good to know: The inequality (!=) operator cannot be chained in a Notion formula. A formula like 1 != 2 != 3 won’t work. Use the and operator to get around this – e.g. 1 != 2 and 2 != 3.

The example database below contains a Cat Status property that will inform you on whether or not your lawyer is a cat.

(prop("Type") != "Cat") ? "Your lawyer is not a cat." : "Your lawyer is a cat."
