Table of Contents

What is ASCII?

ASCII (American Standard Code for Information Interchange) is a character encoding standard that represents text in computers and other devices. Originally developed in the 1960s, ASCII uses 7 bits to represent 128 characters (0-127), including letters, digits, punctuation marks, and control characters.

Extended ASCII uses 8 bits to represent 256 characters (0-255), adding 128 additional characters for special symbols, accented letters, and other international characters. The Extended ASCII set varies by encoding (like ISO-8859-1 or Windows-1252), but this table shows the standard Extended ASCII character set.

Each ASCII character has multiple representations:

  • Decimal (0-255): The standard numeric representation, most commonly used in programming
  • Hexadecimal (0x00-0xFF): Base-16 representation, commonly used in memory addresses and binary data
  • Octal (000-377): Base-8 representation, less common but still used in some systems
  • Binary (0b00000000-0b11111111): Base-2 representation, showing the actual bit pattern
  • HTML Entity: The HTML representation for use in web pages (e.g., &#65; for 'A')
  • Character: The visual representation of the character itself

ASCII Character Sets

Control Characters (0-31, 127)

The first 32 characters (0-31) and character 127 are non-printable control characters used for device control and formatting. These include:

  • NUL (0): Null character, used as string terminator in C
  • HT (9): Horizontal tab
  • LF (10): Line feed (newline)
  • CR (13): Carriage return
  • ESC (27): Escape character
  • DEL (127): Delete character

Printable ASCII (32-126)

Characters 32-126 are printable ASCII characters, including:

  • Space (32): The space character
  • Punctuation (33-47, 58-64, 91-96, 123-126): Various punctuation marks
  • Digits (48-57): Numbers 0-9
  • Uppercase Letters (65-90): A-Z
  • Lowercase Letters (97-122): a-z

Extended ASCII (128-255)

Characters 128-255 are Extended ASCII characters, including:

  • Extended Control (128-159): Additional control characters (varies by encoding)
  • Extended ASCII (160-255): Special symbols, accented letters, and international characters

Note: This table uses Windows-1252 (CP-1252) encoding names for characters 128-159. The actual characters displayed may vary depending on your browser and system encoding. Modern systems typically use UTF-8, which is backwards-compatible with standard ASCII (0-127) but represents characters 128+ differently.

Common Use Cases

  • Character Encoding: Understanding how characters are represented in different number systems (decimal, hex, octal, binary) is essential for working with character encodings, file formats, and data processing.
  • String Manipulation: Converting between character codes and characters is common in programming. Functions like charCodeAt() and fromCharCode() in JavaScript use ASCII values.
  • Data Validation: Checking if characters fall within specific ranges (e.g., alphanumeric: 48-57, 65-90, 97-122) is useful for input validation and data cleaning.
  • HTML Development: HTML entities allow you to display special characters that might conflict with HTML syntax or aren't easily typed on keyboards.
  • Debugging: When debugging character-related issues, knowing the exact ASCII value helps identify problems with encoding, special characters, or control characters.
  • File Processing: Binary file formats often use specific ASCII values as delimiters, markers, or control codes. Understanding these values is crucial for parsing files correctly.
  • Network Protocols: Many network protocols use ASCII control characters (e.g., CRLF for line endings) or specific ASCII values for protocol-specific purposes.
  • Cryptography: Character encoding knowledge is important in cryptography, where characters are often converted to numeric values for mathematical operations.

Frequently Asked Questions

What's the difference between ASCII and Extended ASCII?

Standard ASCII uses 7 bits and represents 128 characters (0-127). Extended ASCII uses 8 bits and represents 256 characters (0-255). The Extended ASCII set adds 128 additional characters for special symbols, accented letters, and international characters. However, Extended ASCII encoding varies by system (ISO-8859-1, Windows-1252, etc.), while standard ASCII is universal.

Why are some characters shown as control codes instead of the actual character?

Control characters (0-31, 127) are non-printable characters used for device control and formatting. They don't have visual representations, so we show their control names (like NUL, HT, LF) instead. Character 32 (space) is shown as [SP] for clarity, though it is printable.

How do I use HTML entities in my code?

HTML entities can be used directly in HTML code. For example, &#65; displays as 'A', and &nbsp; displays as a non-breaking space. You can copy the HTML entity from the table and paste it directly into your HTML code. Some characters have named entities (like &nbsp;), while others use numeric entities (like &#65;).

What encoding does this table use for Extended ASCII?

This table shows the standard Extended ASCII character set. The actual characters displayed for codes 128-255 may vary depending on your system's character encoding (UTF-8, ISO-8859-1, Windows-1252, etc.). Modern systems typically use UTF-8, which extends beyond 255 characters and supports Unicode. The numeric values (decimal, hex, octal, binary) are universal regardless of encoding.

How do I convert between different number systems?

You can use the table to see all representations of a character. For example, the letter 'A' is:

  • Decimal: 65
  • Hexadecimal: 0x41
  • Octal: 0101
  • Binary: 0b01000001

In programming, you can convert between these using built-in functions. For example, in JavaScript: parseInt('41', 16) converts hex to decimal, and (65).toString(16) converts decimal to hex.

What are the most commonly used ASCII values?

Some of the most commonly used ASCII values include:

  • 32: Space
  • 48-57: Digits 0-9
  • 65-90: Uppercase letters A-Z
  • 97-122: Lowercase letters a-z
  • 10: Line feed (newline)
  • 13: Carriage return
  • 9: Tab
  • 0: Null terminator (used in C strings)
Can I search for characters by their description?

Yes! The search function searches across all columns including descriptions. You can search for terms like "control", "digit", "uppercase", "punctuation", etc., to find all characters matching that description. You can also search by decimal value, hex value, character, or any other field.
