This decoder converts numeric character codes back into readable text. Input can be separated by spaces, commas or new lines, so a list copied from a debugger, a spreadsheet column or a code array all work without reformatting. Values from 0 to 127 map to classic ASCII, while higher numbers are treated as Unicode code points, which means 233 produces é and 128512 produces 😀. Out-of-range or non-numeric entries are flagged with their position rather than being silently skipped, so a truncated dump is obvious immediately. Typical uses are reconstructing a string from a memory dump, checking a coursework answer, or solving a puzzle where a message is hidden as numbers.
