Decimal to ASCII Converter
Turn a numeric code point into the character it represents.
A decimal to ASCII converter takes a numeric code point and returns the character it stands for. Codes 0–127 cover classic ASCII letters, digits, and punctuation, while larger values reach the wider Unicode range. Enter a decimal code below to see its character, or use the reverse tool to look up the code for a character.
How to convert a decimal code to a character
- Type a decimal code point (for example 65) into the Decimal code point field.
- The matching character appears in the Result field.
- Use the copy button, or the reverse tool below to go from a character back to its code.
Worked example: 65 is "A"
Code 65 maps to the capital letter A. The lowercase a sits 32 places higher at 97, which is why flipping a single bit (value 32) switches letter case. Code 48 is the digit 0, and 32 is the space character.
Reference table
| Decimal | Character | Hex |
|---|---|---|
| 32 | space | 20 |
| 33 | ! | 21 |
| 48 | 0 | 30 |
| 57 | 9 | 39 |
| 65 | A | 41 |
| 90 | Z | 5a |
| 97 | a | 61 |
| 122 | z | 7a |

Frequently asked questions
- What is ASCII code 65?
- Decimal 65 is the capital letter A. The uppercase alphabet runs from 65 (A) through 90 (Z) in order.
- What is the difference between ASCII and Unicode?
- ASCII defines codes 0–127 for English letters, digits, and control characters. Unicode extends far beyond that to cover virtually every script and symbol, and this tool accepts code points up to 1114111.
- Why is the space character a code at all?
- A space is a printable character with its own code, decimal 32 (hex 20). Codes below 32 are non-printing control characters such as tab and newline.
- How do I convert a character back to its code?
- Use the reverse Character to decimal tool on this page: type a single character and it returns the code point. For example A returns 65.
