FAQ
- What separator is used?
- Dot (.) is the default separator, but you can configure custom separators.
- What if a key name itself already contains the delimiter character, like a dot?
- If a key name (not the value) already contains the same character used as the delimiter, the path can get split in the wrong place during flatten or unflatten. In that case, switch the delimiter to something that doesn't appear in your data, like / or _.
