How your JSON is converted

  • Feed it an array of objects: each field name turns into a column header and each object into a row.
  • Nested objects are flattened into dotted column names (address.city), so the file opens neatly in Excel or Google Sheets.

JSON and CSV in brief

  • JSON is the data format behind web APIs and JavaScript apps: records made of named fields that can sit inside one another.
  • CSV is a table saved as plain text: one line per row, with commas separating the values. Excel, Google Sheets, online banking and most databases export it.

Worth knowing

  • There's no software to install and no account to create. Everything runs inside the browser tab, so it behaves the same on Windows, Mac, Linux, iPhone, Android and Chromebook.
