ASCII Table The ASCll code is used to give to each symbol/key from the keyboard a unique number called ASCll code. It can be used to convert text into ASCll code and then into binary code.It can be used within your code to identify specific characters in a string or specific keys being pressed on the keyboard. The ASCll table contains 256 codes(from 0 to 255).The table below only shows the most useful ASCll codes.
