ISEMPTY
Returns true if the expression is empty.
- Strings passed into the function are checked if they are an empty string.
- If an array is passed into the function, the function will return true only if every item in the flattened array is equal to the empty string.
- If a value that is not a string or array is passed into the function, the value will be converted to a string before checking if the value is an empty string.
- If an object is passed into the function, the function will return true only if the object has no keys.

Examples
=ISEMPTY("") → true
Checks if the string "" is empty.
=ISEMPTY(123) → false
Checks if the number 123 is empty. 123 is converted to the string "123", which is not empty and the function returns false.
=ISEMPTY(@"Property 1") → false
Checks if the shape data property "Property 1" is empty. Because "Property 1" is not empty (it has the value 1), the function returns false.
=ISEMPTY(@"Property 4") → true
Checks if the shape data property "Property 4" is empty. Because "Property 4" is empty, the function returns false.
=ISEMPTY(OBJECT("A", 2)) → false
Checks if the object is empty, and because the object has a key-value pair the function returns false.
