ASCII Character Table

ASCII Table / ASCII Character Codes: stands for "American Standard Code for Information Interchange". These are the numeric codes that represent a character, every character has it's ASCII code.

What is ASCII?

ASCII is a character encoding standard to provide a standard way for digital machines to encode characters. It is a mechanism to convert alphabets, digits, punctuation, and special characters into a special code (ASCII) that can understand (decode) by the digital systems. When it was developed, it has 7 bits representing 128 unique characters and it was later extended to 8 bits representing 256 unique characters (including digits, special characters).

ASCII Table / ASCII Character Codes

Here is the ASCII Table with all ASCII Characters expressed with their Decimal Values, Octal Values, Binary Values, and Hexadecimal Values. Some characters are unprintable in this ASCII Table; you will get detailed information at the bottom of the page.
