ASCII code chart
ASCII code chart in character encoding
A code chart arranges all characters in an encoding into a visual grid, typically 16 columns by 8 or 16 rows, with row and column headers in hexadecimal. Reading off the row and column gives you the character's code point instantly - row 4, column 1 is hex 0x41, which is the letter A (decimal 65).
We offer chart views for ASCII and all 22 supported encodings including CP437, CP1252, and the ISO-8859 family. Each chart color-codes cells by category: control characters, printable characters, and extended characters. The compact grid format makes it fast to spot holes (unassigned positions) and differences between encodings.
