ASCII Code Reference Table - ASCII Character Encoding and Conversion Tool
On this page, you can view a complete ASCII code reference table and use the ASCII code converter for character encoding conversion. ASCII encoding is a widely used character encoding standard worldwide, covering a variety of characters from numbers, letters to symbols, and is widely used in program development, data exchange, and other fields.
What is ASCII code?
ASCII (American Standard Code for Information Interchange) is a 7-bit character set based on English characters, originally used for exchanging text information between computers. It uses numerical values (from 0 to 127) to represent characters, covering standard English characters, numbers, and common symbols. By standardizing the values of these characters, ASCII allows computers to represent and process text consistently.

How to use the ASCII code converter?
Our ASCII code converter provides the convenient function of character encoding conversion. You simply input a character, and the converter will automatically display its corresponding ASCII code; conversely, you can also input an ASCII code, and the converter will return the corresponding character.
Character to ASCII code example:
Input character “A”, the converter will return the corresponding ASCII code: 65.
ASCII code to character example:
Input ASCII code “65”, the converter will return the corresponding character: A.
Difference between ASCII and ANSI character sets
ASCII encoding uses 7 bits to represent characters, containing 128 characters (from 0 to 127). On the other hand, ANSI encoding is an extension of ASCII, supporting more characters and symbols, typically using 8 bits or more to represent characters, covering a broader range of languages and symbols.
Applications of ASCII code
ASCII code is widely used in computer programming, file formats, data transmission, and many other fields. It is the basis of various computer languages, ensuring that text information can be correctly exchanged between different systems and platforms.
Frequently Asked Questions
1. What is the difference between ASCII code and Unicode?
ASCII code uses 7 bits to represent characters, supporting only English letters, numbers, and some symbols; while Unicode encoding uses a larger character set, supporting all the language characters in the world.
2. What is the character range of ASCII code?
ASCII code ranges from 0 to 127, covering basic English characters, numbers, symbols, and control characters.
3. How to use ASCII encoding in programming?
In programming, you can use ASCII codes to represent characters, and many programming languages (like Python, C++, Java) provide related functions and methods to convert between characters and ASCII codes.
Conclusion
ASCII code is a widely used character encoding standard in computers, and learning and understanding ASCII code is fundamental to computer programming and data exchange. Our ASCII code reference table and ASCII code converter tools can help you quickly look up and convert characters and ASCII codes, facilitating program development, text processing, and data exchange.
