# TRIM ### Description TRIM removes whitespace (like " ") from the beginning or end of a string. Optionally, you can also provide a second argument of the characters you would like to remove. If you only want to remove characters from the left, consider using [`TRIM_LEFT`](/rule-language/operators/string-operators/trim_left.md). ### Example ``` TRIM(' I like Atfinity ') ``` This will remove the spaces before and after leaving only the text `'I like Atfinity'` without the spaces behind. ### Example with custom character ``` TRIM('__hello__', '_') ``` This will remove the underscores before and after leaving only the text `'hello'` without the spaces behind. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
