ASCII Table
| Dec | Hex | Oct | Bin | Char | Description |
|---|
This complete ASCII table lists every one of the 128 standard ASCII characters with its decimal, hexadecimal, octal, and binary values. Use the search box to find any character or code instantly — a practical reference for decoding, encoding, and data work.
How to Read the ASCII Table
Each row of the table shows one character together with the four common ways to represent it numerically. The Hex column is the value you will see in hex dumps and protocols, while the Dec and Bin columns help you cross-check conversions.
For example, the uppercase letter A appears as 65 in decimal, 41 in hex, 101 in octal, and 01000001 in binary. Because each value describes the same character, the ASCII table doubles as a quick conversion reference.
- Uppercase letters span 65-90 (0x41-0x5A).
- Lowercase letters span 97-122 (0x61-0x7A).
- Digits 0-9 span 48-57 (0x30-0x39).
- Control characters occupy codes 0-31, plus 127 for DEL.
- Use the search box to locate a character by code or name.
Why Use the ASCII Table?
The ASCII table is one of the most-used references in computing. It is the foundation for text encodings, hex to text conversion, and countless debugging tasks where you need to translate between a raw byte and the character it represents.
Keep this interactive ASCII chart accessible whenever you are inspecting data files, writing character parsing code, or learning how computers encode text.
