About ASCII Table

ASCII (American Standard Code for Information Interchange) is the foundational character encoding for text in computers. This reference table lists all 128 ASCII characters with their decimal, hexadecimal, octal, and binary values. Use the search feature to quickly find any character by name, symbol, or code. Essential for low-level programming, data analysis, and understanding text encoding.

How to Use

  1. Browse the full table of 128 ASCII characters.
  2. Use the search bar to find characters by name, code, or symbol.
  3. View decimal, hex, octal, and binary values for each character.

Key Features

  • ✓ Complete 128-character ASCII table
  • ✓ Decimal, hex, octal, and binary values
  • ✓ Searchable by character name or code
  • ✓ Control character descriptions

Common Use Cases

  • • Looking up character codes for programming
  • • Understanding control characters in protocols
  • • Converting between character representations
  • • Learning about text encoding fundamentals

Frequently Asked Questions

What is ASCII?

ASCII is a 7-bit character encoding standard that assigns numbers 0–127 to letters, digits, punctuation, and control characters. It was first published in 1963 and remains the foundation of modern text encoding.

What are ASCII control characters?

Characters 0–31 and 127 are control characters (like NUL, TAB, LF, CR, ESC). They were originally used to control hardware devices like printers and terminals.

What is the difference between ASCII and Unicode?

ASCII covers 128 characters (English only). Unicode extends this to over 149,000 characters covering virtually every writing system. The first 128 Unicode code points are identical to ASCII.

What is the difference between ASCII and UTF-8?

UTF-8 is a variable-length encoding for Unicode. For ASCII characters (0–127), UTF-8 uses the same single byte as ASCII, making it backward compatible.
