length
Learn how to use the length function in Notion formulas.
The length() function outputs a number that corresponds to the length of a string.
1
length(string)

1
length("Monkey D. Luffy") // Output: 15
2
3
length("Supercalifragilisticexpialidocious") // Output: 34
4
5
length("Doctor Doom") // Output: 11

This example database used the length() function to return the number of characters in the Name property. It also uses an if statement to intelligently output “character” or “characters”.

This formula first uses the length() function to get the number of characters in the Name property. This is wrapped in the format function in order to convert the number to a string.
Second, an if statement again uses length() to check whether or not the number of characters in the Name property is equal to 1. If so, it outputs the singular “character”. If not, it outputs the plural “characters.”
