Convert Text to ASCII (UTF-8) and ASCII Number to Text (UTF-8)

Convert any language text to ASCII number format or ASCII codes to Normal Text instantly with this free in-browser tool. For example: A is 065 / 0065. ASCII is short of American Standard Code for Information Interchange. Computers can only understand numbers, and ASCII codes are numerical representations of characters that a computer can understand. Text in a computer is stored as numbers called ASCII numbers with each letter having its own defined number.

This online tool support Multibyte String or Unicode (UTF-8) Character in Conversion. Type / Paste / Upload your ASCII Numbers data or text data into related textarea for convertion. Separate your ASCII codes data with a comma, a space (which include " ", \r, \t, \n and \f), -, /.

What is ASCII Numbers?

ASCII (American Standard Code for Information Interchange) is a character encoding system that represents characters using 7-bit binary numbers. It was developed in the 1960s to standardize the way computers and other devices represent and exchange text-based information.

ASCII uses 128 unique values (0-127) to represent letters, digits, punctuation marks, and other common characters used in the English language. Each value represents a specific character, such as the letter 'A' (value 65), the digit '0' (value 48), or the punctuation mark '$' (value 36).

The ASCII character set includes:

• 33 control characters (0-31 and 127)
• 10 digits (0-9)
• 26 uppercase letters (A-Z)
• 26 lowercase letters (a-z)
• 32 punctuation marks and symbols (such as !, @, #, etc.)
• 1 space character (value 32)

ASCII codes can be represented in various formats, such as binary, decimal, and hexadecimal. For example, the ASCII code for the letter 'A' can be represented as:

• Binary: 01000001
• Decimal: 65
• Hexadecimal: 41

ASCII is still widely used today, especially in legacy systems and in programming. However, its limited character set and lack of support for non-English languages have led to the development of other character encoding systems, such as Unicode, which supports a much larger set of characters and scripts from around the world.

How to convert a string to ASCII Numbers manually?

To convert a string to ASCII numbers manually, you can use an ASCII chart to look up the decimal value associated with each character in the string. Here are the steps:

1. Write down the string you want to convert to ASCII numbers.
2. Look up the ASCII decimal value for each character in the string using an ASCII chart. For example, the decimal value for the letter 'A' is 65.
3. Write down the decimal values for each character in the string in order. This will give you the ASCII representation of the string.

Here's an example of converting the string "Hello, world!" to ASCII numbers:

So the ASCII representation of "Hello, world!" would be: 072 101 108 108 111 044 032 119 111 114 108 100 033

How to convert a text to ASCII Numbers in Javascript?

To convert a text string to ASCII numbers in JavaScript, you can use a loop to iterate over each character in the string and then use the `charCodeAt()` method to get its ASCII decimal value. Here's an example function that does this:

function textToAscii(text) { let ascii = ''; for (let i = 0; i < text.length; i++) { let code = text.charCodeAt(i); ascii += code.toString() + ' '; } return ascii.trim();} 

This function takes a text string as input and returns a new string containing the ASCII decimal values of each character in the input string, separated by spaces. The `charCodeAt()` method is used to get the ASCII decimal value for each character, and the `toString()` method is used to convert it to a string. The resulting ASCII value is concatenated with a space and added to the `ascii` string.

let text = 'Hello, world!';let ascii = textToAscii(text);console.log(ascii); // outputs: 072 101 108 108 111 044 032 119 111 114 108 100 033 

In this example, the input string 'Hello, world!' is converted to its ASCII decimal values using the `textToAscii()` function. The resulting string of ASCII values is then printed to the console.

List of ASCII Numbers Applications and Uses

ASCII (American Standard Code for Information Interchange) has been widely used in various applications for several decades. Here are some of the most common applications and uses of ASCII numbers:

1. Communication protocols: ASCII is commonly used in communication protocols between computers and other electronic devices, such as modems and printers. This is because ASCII provides a standardized way to represent text-based information, making it easier to exchange data between different systems.
2. Programming languages: Many programming languages, including C, C++, Java, and JavaScript, use ASCII codes to represent characters in strings and other text-based data.
3. File formats: ASCII is used in various file formats, such as text files and CSV (Comma Separated Values) files, to represent text-based data.
4. Data transmission: ASCII is often used to represent data that is transmitted over the internet or other networks. For example, email messages are typically encoded using ASCII, as are web pages and other online content.
5. Character recognition: ASCII codes are sometimes used in character recognition software, such as optical character recognition (OCR) systems, to convert scanned text into digital format.
6. Debugging: ASCII codes are often used in debugging software to help identify issues with text-based data, such as encoding errors or data corruption.
7. Control codes: The first 32 ASCII codes (0-31) are reserved for control characters, which are used to control devices such as printers and modems. These codes are still used in some applications today, such as in terminal emulation software.
8. Barcode scanning: ASCII is used in barcode scanners to read and interpret the ASCII-encoded text on a barcode label.
9. Printing: ASCII is used in printers to generate printed text, such as reports, invoices, and labels.
10. Character encoding: ASCII is used as a basis for many other character encoding systems, such as ISO-8859, Windows-1252, and UTF-8.
11. Legacy systems: ASCII is still widely used in legacy systems and applications that were developed before the advent of Unicode and other modern character encoding systems.
12. Data analysis: ASCII codes can be used to represent and analyze text-based data, such as in natural language processing and sentiment analysis.

Overall, ASCII has been a fundamental part of computing for many years, and its standardized character encoding system has helped to make text-based communication and data exchange more reliable and efficient.
