About JSON to CSV
Convert a JSON array of objects into a CSV file. The tool flattens nested fields with dot notation by default, or you can pick which top-level keys become columns.
Frequently asked questions
What if my JSON isn't an array?
Wrap the object in [ ... ] or paste a single object - the tool treats it as a one-row CSV.
How are nested arrays handled?
By default they're joined with a pipe (`|`). You can also expand each array element into its own row.
