How to convert words and text to decimal ASCII code?

Switch to 'Text to Decimal' mode. Type or paste your text. For each character, the tool extracts its character code using codePointAt() or charCodeAt() and outputs space-separated decimal values.

What is the ASCII to decimal table range?

Standard ASCII spans decimal values 0 through 127. Values 0-31 and 127 are non-printable control characters (like Tab, Line Feed, and Carriage Return). Values 32 through 126 represent printable characters including numbers (48-57), uppercase letters (65-90), and lowercase letters (97-122).

Decimal to ASCII Text Converter

Complete Guide: Decimal to ASCII Code & Character Conversion

Welcome to the developer-first decimal to ascii calculator and online text to ascii converter. In computer science and digital telecommunications, every letter, number, and punctuation symbol has an underlying numeric value. When you need to convert decimal to ascii code, translate raw numeric data streams with a decimal to text converter, or use an int to ascii converter in C/C++, Java, or Python, this tool delivers instant, reliable decoding.

How to Convert Decimal Numbers to ASCII Characters

The standard ASCII encoding system maps numbers 0 through 127 to specific glyphs:

65 – 90: Uppercase English letters (A through Z)
97 – 122: Lowercase English letters (a through z)
48 – 57: Digits 0 through 9
32: Space character
33 – 47, 58 – 64: Punctuation and symbols (!, @, #, etc.)

For example, entering 72 101 108 108 111 into our decimal to ascii text converter produces Hello.

Reverse: How to Convert Words to ASCII (Text to Decimal)

Need to convert words to ascii or find a character to ascii converter? Each letter in your word corresponds to its integer ASCII index:

'C' (67) + 'a' (97) + 't' (116) = 67 97 116

Frequently Asked Questions (FAQ)

What is the difference between decimal to char and integer to ascii?

In programming, decimal to char typecasts an integer directly to its ASCII character glyph (e.g. (char)65 becomes 'A'). In contrast, itoa (integer to ASCII) converts the number 65 into the two-character string "65". Our tool handles character glyph decoding and reverse text encoding.

Can this tool handle numbers above 127?

Yes! Standard ASCII is defined from 0 to 127. Values from 128 to 255 belong to Extended ASCII (ISO-8859-1 / Windows-1252), and numbers beyond 255 represent Unicode code points (such as emojis or Asian CJK characters). Our tool seamlessly supports full Unicode character decoding.
