Frequently Asked Questions

Which JSON shapes convert?

An array of objects becomes a table. A single object becomes one row. An array of strings or numbers becomes one value column.

Are nested objects flattened?

No. A nested object or array is written as JSON text in that cell so the conversion does not invent columns.
