ASCII Table Reference

The ASCII Table Reference is a fast, searchable lookup for the full 7-bit ASCII set, codes 0 through 127.

Every row shows the character itself alongside its decimal, hexadecimal, octal and 8-bit binary representations, so you can switch between number bases without reaching for a calculator.

Control characters such as NUL, TAB, LF, CR and ESC are labelled by name and flagged so you can tell them apart from printable glyphs at a glance.

The search box matches across everything at once: type a letter to find its codes, a number like 65 to jump to capital A, a hex value like 41, or part of a description such as "carriage" to surface the carriage return.

This makes the table just as useful for debugging a serial protocol or a text encoding bug as it is for everyday programming reference.

Like every My Tools Garage tool it is entirely client-side.

The whole table is built in your browser, nothing is fetched from a server, and it keeps working offline once loaded.

There is no tracking and nothing to type that ever leaves your machine, so it is a dependable companion whether you are at your desk or on a locked-down build box.
