JSON (JavaScript Object Notation) is a lightweight data interchange format widely used in APIs and web applications. CSV (Comma-Separated Values) is a tabular format supported by spreadsheet programs like Excel and Google Sheets. Converting JSON to CSV is essential when you need to analyze API data in a spreadsheet or import it into database tools.

How to Use

  2. Click "Convert".
  3. Copy or download the CSV output.

FAQ

How are nested objects handled?

Nested objects and arrays are serialized as JSON strings in the CSV output, so no data is lost.

What if objects have different keys?

All unique keys across all objects are collected as CSV headers. Missing values are left empty.
