Use this text tool to remove any specific unwanted characters or letters. Just type the characters you want to be removed in the text box and click remove. No need to add separators like commas, or escape characters. There are also several templates readily available for you to use.
Note: All templates excluding "All non-alphanumeric" can be modified to your needs. If you have a specific set of characters that you want to remove, use the "Blank template".
