+### Trim

+```Trim(target, Optional[replacement])```
+
+The `Trim` Converter removes the leading and trailing character (default: a space character).
+
+If the `target` is not a string or does not exist, the `Trim` Converter will return an error.
+
+`target` is a string.
+`replacement` is an optional string representing the character to replace with (default: a space character).

 Examples:
 
-- `Split("A|B|C", "|")`
+- `Trim(" this is a test ", " ")`
+- `Trim("!!this is a test!!", "!!")`
 
 ### String
