How It Works
ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns numeric values to letters, digits, punctuation, and control characters. Standard ASCII uses 7 bits to represent 128 characters (0-127).
Common ASCII values include: A=65, Z=90, a=97, z=122, 0=48, 9=57, space=32. When converting text to ASCII, each character is replaced by its decimal code number, separated by spaces.
When converting ASCII to text, the tool reads space-separated decimal numbers and converts each to its corresponding character using String.fromCharCode().
