What is the ASCII Converter?

Every character a computer displays maps to a numeric code point — the first 128 (0-127) are the original ASCII set; this tool converts text to its decimal code points, or a list of codes back to text.

How to use it

  1. 1 Choose a direction.
  2. 2 Enter text (to get codes) or space/comma-separated codes (to get text).

Limitations

  • •Supports the full Unicode range, not just the original 128-character ASCII set — codes above 127 represent extended/Unicode characters, not classic 7-bit ASCII.

Frequently asked questions

What's the difference between ASCII and Unicode code points here?

Classic ASCII only covers codes 0-127; this tool uses JavaScript's full Unicode code point support, so it correctly handles accented letters, symbols and emoji too, not just the original ASCII range.
