lowercase

Converts a string to lowercase.

Syntax

lowercase(s)

Parameters

Name	Type	Required	Description
s	string	Yes	The string to convert to lowercase.

Returns

Type: string

The input string with all characters converted to lowercase. Returns an empty string if the input is not a string.

Examples

Normalize an email field:

lowercase([email])

If email is "[e-mail]", the result is "[e-mail]".

Case-insensitive comparison by lowering both sides:

lowercase([status])

If status is "ACTIVE", the result is "active".

Notes

• If the input is not a string (e.g., a number or None), the function returns an empty string "" rather than raising an error.
• This function applies the standard Unicode lowercase transformation, so it works correctly with accented and international characters.
