Support for unflattening (e.g. reverse operation) about flatten HOT 2 CLOSED

Hmm, we lose information in flattening, would have to name appropriately.

Do you have a specific example use case?

from flatten.

Unflattening should be useful in such a use case:

1. I need a flattened json string to store all key values.
2. I want to combine multiple sources of data into one json file, then add corresponding prefix for each flattened key. for example, {"facebook.username": "abc", "facebook.userpost": 5, "twitter.username": "xyz", "twitter.userpost": 20, ...}.

Unflattern may help user to reconstruct the struct and ease to operate if unmarshal is needed.
