About Text to ASCII Code Converter

This tool converts any text string into its corresponding ASCII (American Standard Code for Information Interchange) or more broadly, Unicode code point values. You can choose to view these codes in various numerical bases: Decimal, Hexadecimal, Binary, or Octal. You can also customize the separator used between the codes for each character.

ASCII codes are numerical representations of characters. Standard ASCII covers characters 0-127, while extended ASCII often covers 0-255. This tool uses charCodeAt(0) which returns the UTF-16 code unit, aligning with ASCII for the common character set and providing Unicode values for others.

How to Use This Tool

  • Enter or paste the text you want to convert into the "Enter Text" input area.
  • Select your desired "Output Format" (Decimal, Hex, Binary, or Octal).
  • Choose a "Separator" to be placed between each character's code (Space, Comma, Newline, None, or Custom).
  • If you select "Custom" separator, an input field will appear for you to type your desired custom separator.
  • The ASCII codes will be generated automatically in the "Output ASCII Codes" area as you type or change options. You can also click "Convert Text".
  • Use the "Copy ASCII Codes" or "Download ASCII Codes" buttons to save your result.

All conversions are performed client-side in your browser for speed and privacy.

Frequently Asked Questions

What is ASCII?

ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns numerical values to letters, numbers, punctuation marks, and other characters. Standard ASCII uses 7 bits for 128 characters. This tool shows the Unicode code point via charCodeAt(0), which is compatible with ASCII for the first 128 characters.

Why would I convert text to ASCII codes?

Converting text to ASCII codes can be useful for various purposes, including:

  • Understanding how characters are stored and represented digitally.
  • Debugging data transmission or encoding issues.
  • Simple forms of data obfuscation (not for security).
  • Educational purposes in computer science and programming.

What output formats are supported?

This tool can output the character codes in Decimal (base 10), Hexadecimal (base 16, e.g., 4A), Binary (base 2, e.g., 01001010), and Octal (base 8, e.g., 112).

How does the padding work for Hex, Binary, and Octal?

For characters within the common ASCII range (0-255):

  • Hexadecimal values are padded with a leading zero if they are single digit (e.g., 'A' becomes '0A'). For Unicode characters beyond 255, they are padded to at least 4 hex digits.
  • Binary values are padded with leading zeros to ensure they are at least 8 bits long.
  • Octal values are padded with leading zeros to ensure they are at least 3 digits long.

This helps maintain a consistent visual format for common characters.

Is my input text processed on a server?

No. All conversions from text to ASCII codes are performed directly in your web browser using JavaScript. Your input data is never sent to any external server.
