What is ASCII Table?
ASCII is the classic character encoding that assigns a number from 0 to 127 to each letter, digit, punctuation mark and control character. It remains the basis of most modern encodings and shows up constantly in low-level programming and debugging.
This table shows each printable character next to its decimal, hexadecimal and binary value. It's a handy reference when you need a character's code, want to interpret a byte dump, or work with text protocols.
Since it includes the hexadecimal column, it also helps you resolve codes like 0x41 (the "A"), 0x2C (the comma) or 0x20 (the space). To convert any number between arbitrary bases, use the number base converter.
