What if objects have different keys?

The header row includes every key found across all objects; cells for missing keys are left blank.

Does it support nested objects?

Nested values are converted to their JSON string form in the cell, since CSV is a flat format.

What if I paste a single object instead of an array?

Wrap it in square brackets — the tool expects a JSON array of objects.
