How to Convert Binary to ASCII

Converting binary to ASCII is a common task in computer programming. Binary is a base-2 number system that uses only two digits, 0 and 1. ASCII, on the other hand, is a character encoding standard that assigns a unique number to each character. Converting binary to ASCII involves converting each group of 8 bits (1 byte) to its corresponding ASCII character.

Conversion

Here's a step-by-step guide on how to convert binary to ASCII:

1. Choose the binary value you want to convert to ASCII.
2. Divide the binary value into groups of 8 bits (1 byte).
3. Convert each group of 8 bits to its decimal value using the binary-to-decimal conversion method.
4. Look up the ASCII character corresponding to each decimal value using an ASCII table.

Example

Let's walk through an example to illustrate the process. Suppose we want to convert the binary value 10000010100001001000011 to ASCII.

1. The binary value we want to convert is 10000010100001001000011.
2. We divide the binary value into groups of 8 bits: 01000001, 01000010, and 01000011.
3. We convert each group of 8 bits to its decimal value using the binary-to-decimal conversion method. The decimal values are 65, 66, and 67.
4. We look up the ASCII character corresponding to each decimal value using an ASCII table. The ASCII characters are 'A', 'B', and 'C'.
5. The ASCII representation of the binary value 10000010100001001000011 is "ABC".

ASCII-Binary Table

Here's a table of the ASCII characters and their corresponding binary values:

Sample Code

This code requires @ilihub/code npm package to run.

import { BinaryToAscii } from "@ilihub/code";

const binary =
  "0100100001100101011011000110110001101111001000000101011101101111011100100110110001100100";

const ascii = BinaryToAscii(binary);
console.log(ascii);

// Output
// Hello World
