Text ⇄ ASCII Codes
Text ⇄ ASCII Codes converts each character in your text into its decimal ASCII code, or decodes a list of codes back into readable text. It's a handy reference for students learning character encoding, or for developers double-checking how a string maps to numeric codes.
Whether you're studying computer science fundamentals or debugging an encoding issue, this tool gives you an instant answer. Conversion runs entirely as JavaScript in your browser, so nothing you enter is uploaded to a server.
How to Use the Text ⇄ ASCII Codes
- Open the Text ⇄ ASCII Codes tool.
- Type or paste text to convert it to codes, or paste codes to decode.
- Switch between encode and decode direction as needed.
- Copy the converted result.
