Endian Converter
Take a hex stream, group it by chosen width (u16 / u32 / u64), and see big-endian and little-endian renderings side by side, plus the unsigned numeric value of each. Crucial when reading length fields, TLV lengths, or numeric IDs in mixed-endian protocol stacks.

About endianness
Big-endian writes the most-significant byte first. Little-endian writes the least-significant byte first. Smart-card / banking / network protocols typically use BE; x86, ARM, and most file formats use LE. Mixing them is a common source of bugs.
Spec
RFC 1700 (legacy network byte order).
