What is Object Flattening?

Object flattening converts deeply nested JSON structures into a single-level object using dot notation. This is essential for data analysis, importing into spreadsheets, and simplifying complex data structures for database storage.

Frequently Asked Questions

Why flatten objects?

Flattened objects are easier to query, import into SQL databases, and analyze in tools like Excel. They also make data serialization more predictable.

How are arrays handled?

Arrays are flattened with indices (e.g., users.0.name) when enabled, or can be kept as strings. Choose based on your use case.
