Text to Decimal Converter

What Is a Text to Decimal Converter?

A Text to Decimal Converter changes characters into their corresponding Unicode code points expressed as decimal numbers. Computers use numerical character representations to identify text, and Unicode provides a standard system for assigning code points to characters across languages, writing systems, symbols and other forms of text.

This converter is particularly useful for developers, programmers, students and anyone working with character encoding or numerical text representations. It can be used to inspect ASCII values, identify Unicode code points, study character encoding or prepare decimal character data for programming and technical applications.

Why Use Text to Decimal Converter?

Manually looking up the decimal value of every character can be slow and inconvenient. This tool converts an entire piece of text at once and provides a clear sequence of decimal Unicode code points that can be copied and reused.

How to Use the Text to Decimal Converter

Converting text to decimal character codes is straightforward. Enter your text, convert it, and then copy the resulting sequence when needed.

1. Enter Text — type or paste the text you want to convert into the input field.
2. Convert to Decimal — select Convert to Decimal to generate the Unicode decimal code point for each character.
3. Review the Result — check the decimal sequence displayed in the result field.
4. Copy the Result — select Copy Result to copy the decimal values to your clipboard.

Text characters can be represented numerically using Unicode code points. For basic ASCII characters, these values are particularly familiar: the uppercase letter A has the decimal value 65, B is 66, lowercase a is 97, the number 0 is 48, a space is 32, and an exclamation mark is 33. As a result, the text Hello becomes 72 101 108 108 111.

The converter processes each Unicode character independently and produces its Unicode code point in decimal notation. This makes it useful when examining character values, working with ASCII or Unicode data, learning about text encoding, debugging software or preparing numerical character data for technical applications.

How Text Characters Are Converted to Decimal

Unicode assigns a unique code point to each character. A code point is normally written in hexadecimal notation, such as U+0041 for the letter A, but the same value can also be expressed in decimal. U+0041 is decimal 65. This converter obtains each character's Unicode code point and displays the equivalent decimal number.

Text to Decimal vs Text to UTF-8 Bytes

It is important to distinguish Unicode code points from encoded bytes. This converter produces Unicode code points rather than UTF-8 byte sequences. For example, the character é has Unicode code point U+00E9, which is decimal 233. When encoded as UTF-8, however, that same character uses the two bytes C3 A9. These are different representations of the same character.

Understanding Decimal Unicode Values

Unicode code points range from 0 to 1,114,111. The first 128 values correspond to the original ASCII character set, which is why ASCII decimal conversions are so common. Unicode extends far beyond ASCII to provide standard code points for characters and symbols used around the world.

JavaScript strings can contain characters represented internally using UTF-16 code units, so characters outside the Basic Multilingual Plane require special handling. This converter uses JavaScript's Unicode-aware code-point iteration to correctly treat such characters as individual Unicode characters rather than incorrectly splitting a supplementary character into two separate values.

Whitespace and control characters are also converted. For example, a line feed has Unicode code point 10 and a tab has Unicode code point 9. These characters may not produce visible output themselves, but their decimal values can still be represented accurately.
