How JSON to CSV Conversion Works

Array of Objects → Rows and Columns

The converter works best when your JSON contains an array of objects. Each object becomes one row in the CSV file. Each key becomes a column header. For example:

Object keys → CSV column names
Object values → Row values
Multiple objects → Multiple rows

Single JSON objects are also supported and converted into a one-row CSV output.

Handling Nested JSON

If your data contains nested objects or arrays, you may need to flatten the structure first. See our guide on how to flatten nested JSON properly for structured examples.
