Text to ASCII / Unicode Codes

About this calculator

This tool converts each character in your text into its numeric character code — the decimal (and optionally hexadecimal) value that computers actually use to store and process that character, based on ASCII for standard Latin characters and Unicode code points for everything beyond it (accented letters, emoji, Turkish ç/ş/ğ, Cyrillic, CJK, and so on).

Programmers use it to debug encoding issues, look up escape codes for special characters in code, or understand why a piece of text isn't sorting or comparing as expected; students and puzzle-solvers use it for cipher and encoding exercises. Because it distinguishes ASCII (0–127) from the wider Unicode range, it also makes clear which characters are "safe" for older systems and which require UTF-8 or similar encoding.
