What is JSON to CSV?

JSON to CSV conversion flattens an array of objects into rows and columns you can open in Excel, Google Sheets, or any spreadsheet. Each object becomes a row and each key becomes a column header. JSON Reader handles the conversion locally, so large datasets never leave your machine.
