How to use the ascii table

1Search a decimal, hex, character, or name (e.g. 65, 41, A, tab).
2Read the character's decimal, hex, octal, and binary codes.
3Use it to debug encoding, escape sequences, or low-level data.

Frequently asked questions

What is the ASCII value of 'A'?

Uppercase A is decimal 65 (hex 0x41). Lowercase a is 97 (0x61).

What are control characters?

Codes 0–31 and 127 are non-printing control characters — like tab (9), line feed (10), and carriage return (13) — used to control text flow, not display glyphs.

What's the difference between ASCII and Unicode?

ASCII covers 128 characters (0–127). Unicode is a superset that covers virtually every character in every language; the first 128 Unicode code points match ASCII.
