Kaitai Struct: declarative binary format parsing language
Reading and writing binary formats is hard, especially if it’s an interchange format that should work across a multitude of platforms and languages. Have you ever found yourself writing repetitive, error-prone and hard-to-debug code that reads binary data structures from files or network streams and somehow represents them in memory for easier access? Kaitai Struct tries to make this job easier —

Dealing with binary data - HaskellWiki
Handling Binary Data with Haskell Many programming problems call for the use of binary formats for compactness, ease-of-use, compatibility or speed. This page quickly covers some common libraries for handling binary data in Haskell. Bytestrings Everything else in this tutorial will be based on bytestrings. Normal Haskell String types are linked lists of 32-bit characters. This has a number of usef
