How it works

Objects become rows; nested objects use dotted names and nested arrays are kept as JSON in a single cell. Values that could be read as spreadsheet formulas get a safety apostrophe.

What this tool does

Make a CSV spreadsheet export from a JSON array.

Before you start

Use an array of objects for predictable columns; nested values need flattening before a tabular CSV can represent them.
