Frequently asked questions
Does it handle nested JSON objects?
Yes. Nested objects are flattened using dot notation. { "address": { "city": "Delhi" } } becomes column "address.city".
What if JSON keys differ across array items?
All unique keys across all objects are used as columns. Missing values become empty cells.
