ASCII is what connects the web, terminals, and embedded devices. Explore every Toolexe ASCII converter and learn how to use workflows that keep data moving smoothly between old and new systems.
ASCII, which stands for American Standard Code for Information Interchange, assigns numbers to letters so that computers can store, send, and display text in a predictable way. ASCII was first used in the 1960s and is still the standard way to encode control characters, printable symbols, and the Latin alphabet.
ASCII is like a common language: every character, from a space to the letter Z, has a decimal value. When devices agree on those values, they can send messages to each other without any problems. Even though Unicode sets are very large these days, ASCII is still used for configuration files, protocols, and low-level device logs.
Here's a quick look at the ASCII table. Each row shows how to write a single symbol in decimal, hexadecimal, and binary. The full table has 128 codes, but this preview only shows the most used range.
| Decimal | Char | Hex | Binary |
|---|---|---|---|
| 32 | Space | 20 | 00100000 |
| 33 | ! | 21 | 00100001 |
| 35 | # | 23 | 00100011 |
| 48 | 0 | 30 | 00110000 |
| 65 | A | 41 | 01000001 |
| 90 | Z | 5A | 01011010 |
| 97 | a | 61 | 01100001 |
| 122 | z | 7A | 01111010 |

ASCII assigns each control character and printable symbol a number between 0 and 127. The first 32 codes manage actions like line breaks or device control, while the remaining codes cover digits, punctuation, and letters. Because ASCII fits inside a single byte,it became the foundation for early file formats, terminal protocols, and telecom systems.
Toolexe converters parse your input, map each symbol to the correct ASCII value, and expose alternative representations such as hexadecimal or Base64. Most tools operate entirely in the browser using JavaScript, which keeps conversions fast and private.
Suppose you receive the decimal string 72 101 108 108 111. The Decimal to ASCII tool maps those numbers to
the characters H, e, l, l, o. If the payload is instead binary,paste it into the Byte to ASCII decoder to see the same message with bit-level context.
ASCII is still the lingua franca for protocols like HTTP headers, SMTP, and shell scripting. DevOps teams rely on ASCII to keep Kubernetes manifests legible, while embedded engineers debug sensors over serial ports where only ASCII is guaranteed to work. Our converters help you sanitise inputs, enforce safe ranges, and communicate effectively between services.
