Text to ASCII

A text to ASCII converter shows the numeric code behind each character of your text, in ordinary decimal: A is 65, a is 97, a space is 32, so "Hi" becomes 72 105. ASCII — the American Standard Code for Information Interchange, from 1963 — assigned codes 0–127 to English letters, digits, punctuation and control characters, and those assignments still anchor every modern encoding.

The layout is full of deliberate design: digits 0–9 are codes 48–57 (subtract 48 to get the digit's value), and upper/lowercase pairs differ by exactly 32 — one bit — which is why case-insensitive comparison is cheap for computers.

Type or paste text and each character's decimal code appears instantly, space-separated. Characters beyond classic ASCII show their full Unicode code point (é → 233, € → 8364), since Unicode extends the same numbering upward.

Programmers use it to check what charCodeAt() or ord() will return, to debug off-by-one string bugs and comparison quirks (why "Z" < "a" — because 90 < 97), and to build or grade encoding exercises. Puzzle makers use decimal-coded messages as a gentler cousin of binary ones.

Conversion is live and local to your browser. ASCII to Text decodes the other direction; Text to Hex and Text to Binary show the same codes in other bases.
