How it works

Three steps, no setup

1

Paste a JSON array

An array of flat or lightly nested objects works best.

2

Choose a delimiter

Comma, semicolon, or tab, depending on your target spreadsheet locale.

3

Download or copy the CSV

Open it directly in Excel, Sheets, or any data pipeline.

Common questions

Frequently asked questions

What happens to nested objects?
Nested values are flattened using dot notation in the column header so no data is silently dropped.
Do all rows need the same fields?
No — the header row is built from the union of keys across all objects, and missing fields are left blank for that row.
