ASCII (American Standard Code for Information Interchange) maps the numbers 0 to 127 to characters. Codes 0–31 and 127 are control characters (like NUL, LF and CR) that were designed to control devices rather than print, 32 is space, and 33–126 are the printable letters, digits and punctuation used across almost every text format.
This table shows each code in decimal, hexadecimal, octal and binary alongside its character and description. Search by number (65), by character (A) or by control abbreviation (LF) to filter. Everything runs locally in your browser.
