How do you convert ASCII codes to a string?

Feed it “77 111 111” and out comes “Moo”. Each number in the input is read as a character code and mapped to its character, with anything that isn’t a digit treated as a separator, so commas, tabs and line breaks are all fine. Codes above 127 work too: 8364 produces €, since the converter follows Unicode rather than stopping at strict seven-bit ASCII.

How to use the ASCII to String

  1. 1 Paste the character codes in any separated form.
  2. 2 The assembled string builds as the codes resolve to letters.
  3. 3 Check that values over 127 render as the Unicode characters you expect.
  4. 4 Copy the finished string.

What you can use it for

  • Converting hard-coded character codes back to readable text.
  • Decoding numeric data back to a string.
  • Verifying a string-to-ASCII result.
  • Demonstrating code-to-character mapping.

Frequently asked questions

Which separators are allowed?
Anything non-numeric: spaces, commas, semicolons, line breaks or a messy mix. Digit runs are the only thing the parser keeps.
Can it handle codes above 127?
Yes. 233 gives é and 128077 gives a thumbs-up emoji, because codes are interpreted as Unicode code points, not clamped to the ASCII table.
What happens to codes like 9 or 10?
They decode to real control characters: 9 is a tab and 10 a line feed, so they shape whitespace in the output instead of printing a visible symbol.
