To combine REGEX_MATCH and REGEX_REPLACE statements in a custom property in Mixpanel, you can use the IF function along with these regex functions. Here's how you can structure it:LBKSIF(REGEX_MATCH(property, pattern), REGEX_REPLACE(property, pattern, replacement), original_property)LBKSThis structure allows you to first check if a pattern matches using REGEX_MATCH, and if it does, apply REGEX_REPLACE. If the pattern doesn't match, it will return the original property value.Here's an example of how you might use this in practice:LBKSIF(REGEX_MATCH(email, "^[^@​]+@​(.+)$"), REGEX_REPLACE(email, "^[^@​]+@​(.+)$", "$1"), email)LBKSThis example would extract the domain from an email address if it matches the email pattern, or return the original email if it doesn't match.Remember that REGEX_MATCH returns true if the pattern matches any part of the string, while REGEX_REPLACE replaces parts of a string that match a regular expression with a different string Custom Properties Functions.When creating custom properties, you can use the formula bar to define these complex transformations. You can also use Ctrl + Space to see a list of available functions and their descriptions while writing your formula Creating a Custom Property.
