ASCII / Hex Table

Decimal, binary, and hex for every ASCII character, 0 through 127.

Codes 0 through 31, plus 127, are unprintable control characters (things like TAB and LF, a line break) and are shown by name instead of by symbol. Everything from 32 through 126 is a normal, visible character.

Quick lookup by hex pair

Each character's hex code has two digits. The first digit picks the row, the second picks the column; the character where they meet is what that byte represents. For example, 4D is row 4, column D: M. Going the other way, M is in row 4, column D, so its hex code is 4D.

Row = first hex digit, column = second hex digit.
