Frequently asked questions

What if the JSON objects have different fields?

The header row is built from the combined set of keys found across all objects; missing fields for a given row appear blank in that column.

Does this handle nested JSON objects?

Deeply nested values are converted to their JSON string representation within a cell, since CSV itself only supports flat, tabular data.
