How ascii table works
ASCII (American Standard Code for Information Interchange) is a 7-bit character set that assigns a number from 0 to 127 to each character. The first 32 codes (0-31) and code 127 are control characters such as Null, Line Feed and Escape; codes 32-126 are the printable characters — space, punctuation, digits and letters — that make up basic English text.
This tool lists every ASCII code with its character, the decimal value, the hexadecimal value and the 8-bit binary value, plus the official name for control characters and punctuation. Use the range selector to view all 128 codes, just the 95 printable characters, or just the 33 control characters.
The converter works both ways. Enter one or more characters to see each one's ASCII code in decimal, hex and binary, or enter one or more decimal or 0x-prefixed hex codes to see the corresponding characters. Codes above 127 are handled as Unicode code points, so you can also look up extended characters.
