![]() ![]() The test() function allows you to test whether a string contains a substring, the latter of which can be a regular expression. Do this by using a regular expression to remove all characters // except the commas that separate the elements (see the example // database below for an in-depth look at this) replaceAll( "Dog, Cat, Monkey, Bat, Gorilla", "", "") // Output:, // Apply length() + 1 to get the count! test ![]() Without \\b, this would output "Thwas was Sparta" replaceAll( "This is Sparta", "\\bis\\b", "was") // Output: This was Sparta // replaceAll() is a great way to count elements in a string. ReplaceAll( "Dogs Dogs Dogs", "Dogs", "Cats") // Output: Cats Cats Cats // Matches are case-sensitive replaceAll( "Dogs dogs Dogs", "Dogs", "Cats") // Output: Cats dogs Cats // You can use brackets to create a set of characters, // any of which will be matched replaceAll( "Dogs dogs Dogs", "ogs", "Cats") // Output: Cats Cats Cats // You can also create a group with () and then use the | (OR) operator replaceAll( "Dogs dogs Dogs", "(D|d)ogs", "Cats") // Cats Cats Cats // Accepts regex metacharacters, such as "\\b" which denotes "word boundary". The replaceAll() function searches a string for a pattern (which can be a regular expression), and replaces ALL matches it finds with another string. Without \\b, this would output "Thwas is Sparta" replace( "This is Sparta", "\\bis\\b", "was") // Output: This was Sparta replaceAll Replace( "Pogo", "Po", "Dog") // Output: Doggo // Matches the first occurrance, unless otherwise specified replace( "Dogs Dogs Dogs", "Dogs", "Cats") // Output: Cats Dogs Dogs // $ tells the regex engine "start from end of line and work backwards" replace( "Dogs Dogs Dogs", "Dogs$", "Cats") // Output: Dogs Dogs Cats // Matches are case-sensitive replace( "thomas", "t", "T") // Output: Thomas // You can use brackets to create a set of characters, // any of which will be matched replaceAll( "thomas", "homas", "Megatron") // Output: Megatron // You can also create a group with () and then use the | (OR) operator replaceAll( "thomas", "(T|t)homas", "Megatron") // Megatron // Accepts regex metacharacters, such as "\\b" which denotes "word boundary". Examples include concat (combines strings) and dateAdd (adds x units of time to a date).Īrguments are the accepted pieces of data used within functions: Function – pre-defined formulas that you can use to accomplish complex things quickly. ![]() Includes mathematical operators (such as add), Boolean operators (such as not), and the ternary operator (if). Operator – symbols that perform operations on 1-3 operands.Constant – mathematical constants e and π, plus the Boolean values true and false. ![]() Property – other properties that exist in your Notion database.Each link here will take you to a full page in the Formula Reference where you can learn more.
