What happens to nested objects inside a JSON record?

A nested object or array within a field is kept as-is in that cell rather than auto-split into separate columns, so deeply nested JSON is easiest to work with if you flatten it before uploading.

What if my file isn't an array at the top level?

A single JSON object (not wrapped in an array) is converted into a one-row table, one column per top-level key.

Does this use AI, like the PDF and image tools?

No. JSON is already a structured format, so it's parsed deterministically, the same way CSV, XLSX, and XLS are.
