ASCII to Hex Converter

Every character maps to a number, and hexadecimal (base 16) is a compact way to write that number. The letter 'A' is 65 in decimal and 41 in hex; a space is 20. This tool reads each character's code unit with JavaScript's charCodeAt and prints it in uppercase hex, padded to a minimum of two digits and joined by spaces. For plain ASCII and Latin-1 text (code points up to U+00FF) that yields the familiar two-digit-per-character output. Note that it reports UTF-16 code units, not UTF-8 bytes: the character 'e' with an accent (U+00E9) becomes E9 here, whereas its UTF-8 byte encoding would be C3 A9. Characters above U+00FF naturally produce three or four hex digits — the euro sign becomes 20AC. The conversion is handy for debugging text-encoding problems, inspecting control characters, building escape sequences, or working with simple binary or wire protocols where you need to see the raw code behind each glyph. Decoding reverses the process: it splits your input on whitespace and turns each hex token back into its character.
