REPLACE: Replaces part of a text string with a different text string. SUBSTITUTE: Replaces existing text with new text in a string. REGEXMATCH: Whether a piece of text matches a regular expression. REGEXEXTRACT: Extracts the first matching substrings according to a regular expression. If numbers are used as input, convert them to text using the TEXT function. If a number is desired as the output, try using the VALUE function in conjunction with this function. This function only works with text (not numbers) as input and returns text as output.Learn more on how to use RE2 expressions. Google products use RE2 for regular expressions.
