Every ASCII code in decimal, hex, octal, binary and its character. Searchable.
ASCII assigns a number 0-127 to letters, digits, punctuation and control codes. This table shows each code in decimal, hexadecimal, octal and binary, alongside the character it represents.
Type the character (like A) to see it is 65 / 0x41, or type a number to see which character it maps to. Control codes like TAB, LF and ESC are labelled.
Non-printing control characters (NUL, tab, line feed, carriage return, escape, etc.) used for formatting and device control rather than visible text.
