About AsciiTable.xyz

ASCIITable.xyz is a single place where you can find everything about ASCII, ASCII character set, ASCII table, ASCII chart, Extended ASCII table, Windows 1252 charset, ISO-8859 charset etc.

The website lists down all the characters in the ASCII charset along with their decimal, binary, octal, and hex equivalent. It also contains descriptions for all the ASCII characters.

In this website, you’ll also find several tutorials and articles about How to convert decimal to ASCII and vice versa in various programming languages.

What is ASCII?

ASCII stands for American Standard Code for Information Exchange. It is a character encoding standard developed in the early 60’s for representing and exchanging arbitrary text-based information between computers.

Computers can only understand numbers. Therefore, we need a way to encode characters to numeric form. ASCII encodes 128 specified characters into 7-bit integers as shown in the table above.

The ASCII character set contains uppercase and lowercase alphabets from A-Z, numbers from 0-9, some special characters like {'{}[]@$!'}, and some non-printable control characters like newline, backspace etc.

The above table lists the entire 128 ASCII characters and their equivalent number in decimal, hex, octal, and binary form.

ASCII Table

The ASCII table lists down all the 128 characters ranging from 0 to 127 of the ASCII character set.

The ASCII table can be classified into four sections -

Control characters: The characters ranging from 0 to 31 and 127 are device control characters. These characters are unprintable.
Lower and upper case alphabets: The uppercase alphabets (A-Z) range from 65 to 90 in the ASCII table. Lowercase alphabets (a-z) start from 97 and end at 122.
Digits: The digits (0-9) range from 48 to 57 in the ASCII character set.
Special characters: The rest of the characters in the ASCII charset are special characters like !, $, @, { } etc.
