Convert all special characters into alphanumeric text

This tool converts all special characters in your text into alphanumeric text. Special characters are defined as any character that is not a letter, a digit, or whitespace. You can choose to remove all special characters, replace common ones with predefined alphanumeric words (e.g., "@" becomes "at", "&" becomes "and"), replace only specified special characters with a custom placeholder, or convert all special characters using a predefined mapping and then wrap each converted value with a custom format. Simply enter your text and select the conversion mode that suits your needs.

Conversion Modes:

Replace Special Characters with Predefined Words
Replaces common special characters with their alphanumeric word equivalents. For example, "@" becomes "at", "&" becomes "and", "$" becomes "dollar", "%" becomes "percent", "#" becomes "number", etc.

Replace Only Specified Special Characters with Custom Placeholder
Replaces only the special characters you specify with a custom placeholder. Enter a comma‑separated list of special characters (e.g., @, #, $), and provide the custom placeholder text (e.g., [SPECIAL]).
