Enter or paste your ASCII text and get it as hexadecimal numbers, or do the same for hexadecimal numbers and get it as ASCII text.
It is an acronym for the American Standard Code for Information Interchange.
It is a standard seven-bit code that was first proposed by the American National Standards Institute or ANSI in 1963, and finalized in 1968 as ANSI Standard X3.4.
The purpose of ASCII was to provide a standard to code various symbols ( visible and invisible symbols)
In the ASCII character set, each binary value between 0 and 127 represents a specific character.
Most computers extend the ASCII character set to use the full range of 256 characters available in a byte. The upper 128 characters handle special things like accented characters from common foreign languages.
In general, ASCII works by assigning standard numeric values to letters, numbers, punctuation marks and other characters such as control codes.
An uppercase "A," for example, is represented by the decimal number 65."
