Introduction
ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns unique numbers to each character in the ASCII table. These numbers, also known as ASCII codes, can be used to represent text in computers, communications equipment, and other devices. ASCII is the most widely used character encoding standard and is the foundation of modern text encoding. In this article, we will explore the concept of ASCII to Text conversion, its history, and origin, and current usage, and provide a conversion table for reference.
History and Origin
The ASCII standard was first introduced in 1963 by the American National Standards Institute (ANSI). The original ASCII standard consisted of 128 characters, including letters, numbers, punctuation marks, and control characters. It was designed to be a standard encoding for data exchange between different types of computers and devices.
ASCII was later extended to include additional characters, such as the Euro symbol and various accented letters, to support internationalization. In the decades that followed, ASCII has been widely adopted and is still in use today in various forms.
Current Usage
ASCII is still widely used today in various forms, including the ASCII-8BIT encoding used by the Ruby programming language and the UTF-8 encoding which is a variable-width extension of ASCII that supports additional characters. ASCII is also used in various other forms of data exchange, such as in the transmission of electronic mail and in the representation of text on web pages.
ASCII to Text Conversion
ASCII to Text conversion is the process of converting a string of ASCII codes into the corresponding characters. This can be done using a simple lookup table that maps ASCII codes to their corresponding characters. In many cases, this conversion can be performed automatically by the computer or device that is receiving the ASCII data.

Definition
ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns unique numerical values to each of the 128 characters used in modern computer systems. These characters include letters of the alphabet, numbers, punctuation marks, and various other symbols.
History/origin
The ASCII standard was first developed in the 1960s by the American National Standards Institute (ANSI) in order to standardize the way that computer systems encode and transmit text. The original ASCII standard included only 128 characters and was later expanded to include an additional 128 characters, known as extended ASCII.
Current use
ASCII is still widely used today as the standard encoding for text in many computer systems, including Windows and Linux. ASCII is also used in many programming languages, such as C and Python, to represent text. Additionally, ASCII is used in many communications protocols, such as the Transmission Control Protocol/Internet Protocol (TCP/IP), to represent text in network transmissions.
