Notion Formula Examples

📜 Table of Contents:

() - capture group (is automatically assigned a sequential reference number)

replace("Dog Blog", "(Dog) Blog", "$1")
// Output: Dog

replace("Dog Blog", "(Dog) (Blog)", "$2")
// Output: Blog

replaceAll("Jack Sparrow", "^(\\\\w+)\\\\b.*", "$1")
// Output: Jack

Test

(?<name>expression) - named capture group

replace("Jack plays poker", "(?<sup>J).*(oker)", "$<sup>$2")
// Output: Joker

// Named capture groups are still assigned their sequential number
// Note the output when I reference "$<sup>$1" instead of "$<sup>$2"
replace("Jack plays poker", "(?<sup>J).*(oker)", "$<sup>$1")
// Output: JJ

Test

(?:) - non-capturing group

replace("Jack", "(?:Jack)", "$1")
// Output: $1

replace("123", "(\\\\w)(?:\\\\w)(\\\\w)", "$2")
// Output: 3
