This converter shows the decimal code point behind each character in your text: 'A' is 65, 'a' is 97, a space is 32 and a newline is 10. The 32-point gap between uppercase and lowercase is why case conversion in code is often just an addition or subtraction, and codes below 32 are the control characters that cause invisible bugs in imported data. Characters outside the original 7-bit ASCII set are shown as their Unicode code points, so é reports 233 and an emoji reports a value above 128,000. It is a direct way to answer 'what character is actually in this string?' when two visually identical values refuse to match.
