Frequently Asked Questions

What if my JSON isn’t an array of objects?

The tool expects a top‑level JSON array where each element is an object. If the structure is different (e.g., a single object or a primitive), an error message will explain what was found.

How are nested objects handled?

You can switch between two modes: Stringify turns nested values into escaped JSON strings inside a single cell; Flatten expands nested keys using dot‑notation (e.g., address.city) and creates separate columns for each leaf field.

Can I change the field separator?

Yes, a dropdown lets you choose between comma (,), semicolon (;), or tab. The CSV escaping rules adjust automatically.
