This tool provides functionality to convert text to an upside-down representation. It includes a mapping of characters to their respective upside-down counterparts. When the conversion button is clicked, it takes the input text, replaces each character with its upside-down equivalent (if available), reverses the resulting text, and displays it. Additionally, there's a button to copy the upside-down text to the clipboard. The script uses JavaScript for manipulation and interaction with the HTML elements on the page.
