JSON (array of objects)

💡 Converts a JSON array of objects into a spreadsheet — the keys become columns. Nested objects are flattened to dotted column names (e.g. address.city). Everything runs in your browser; your data is never uploaded.

API data tips

🔌

Copy a JSON array from your API or browser network tab and paste it to get an instant spreadsheet.

🧱

🔒

The data is converted in your browser — never uploaded.
