Waiting for JSON

CSV

Paste an array of objects on the left; CSV appears here.

What this does

Paste a JSON array of objects and get CSV you can open in Excel, Google Sheets, or Numbers. Every key becomes a column, even keys that only some objects have. If your JSON is an object with the list inside it, like an API response, the first array of objects is used.

Nested data

With Flatten nested on, an address object becomes address.city and address.zip columns, and a list of objects becomes items.0.name, items.1.name. Turn it off to keep nested values as JSON text in one cell. Lists of plain values always stay in one cell.

Excel and delimiters

Comma is standard. Excel in many European locales expects semicolons; Tab makes a .tsv that pastes cleanly into a spreadsheet. Values with commas, quotes, or line breaks are quoted the RFC 4180 way. The Table view shows the first 200 rows so you can check the result before you download.
