Marzie's Reference Tools: ASCII Chart

ASCII, the American Standard Code for Information Interchange, was developed in the 1960's as a standard 7-bit code for identifying letters, numbers, symbols, and special characters in the English language. It was later expanded (as Extended ASCII) to include additional symbols and foreign language characters.

Standard ASCII consists of 128 "characters", ranging from 0 to 127. They can be broken down into a few subgroups:

0 to 31, 127
Control codes (backspace, carriage returns, and others)
32 to 47, 58 to 64, 81 to 86, 123 to 126
Punctuation marks, mathematical (and other) symbols
48 to 57
Numbers 0 through 9
65 to 80
Capital letters A through Z
87 to 122
Lower case letters a through z

Standard ASCII Chart

The chart includes the ASCII character or control and their related decimal and hexidecimal values. The control codes include their meaning, if known.
