Frequently Asked Questions
Our tool automatically flattens nested JSON objects. For example, {"user": {"name": "Amit"}} becomes a column named user.name with the value Amit.

You can choose your strategy in the options bar. "Join in Cell" will put array items like ["JS", "Python"] into a single cell as "JS, Python". "Expand to Rows" will create a new row for each array item.
