Use the normalised output and byte statistics to identify encoding formats or truncation issues quickly.

Check the “Bytes” value to confirm payload sizes when comparing uploads or API parameters.
Switch grouping to produce formats like 0xAB or ABCD that can be pasted into source code or specs.
If decoding fails, remove separators or verify the length is even before retrying.
