Something I find myself doing repeatedly is implementing arcane protocols that were created long before JSON. Bit-packed mainframe protocols. After the second or third time of working with another binary format, there's no new knowledge to gain, and it's not interesting work. But it requires meticulous attention to detail and can't be automated. Most industries don't require you to solve this specific problem but it's all variations of this. Shuffle data from one format to another format. Even if it's JSON, you're still moving it from one business domain to another, or one tech stack to another. Backend to frontend. Etc.
