Palindrome Checker Formula / How It Works

The tool strips non-alphanumeric characters and spacing, converts to lowercase, reverses the characters, and checks equality with the original.

Formula:Cleans string of spaces/punctuation, reverses it, and compares it to the original cleaned string.
Example Calculation:

For example, let's look at the phrase "A man, a plan, a canal: Panama" entered in the checker. By entering these values into the tool, you will get a "Yes, it is a palindrome" result, with the parsed clean string "amanaplanacanalpanama" instantly.
