How JSON maps to CSV
The converter applies clear rules so you can understand the output before using it in another tool or workflow.
Objects become rows
A JSON array of objects becomes multiple CSV rows. A single JSON object becomes one row with its property names as column headers.
Nested keys are flattened
Nested object fields use dotted column names such as user.name, which keeps their path understandable in a flat table.
Complex cells stay readable
Arrays are written as JSON text inside a CSV cell, while commas, quotes, and line breaks are escaped with standard CSV quoting.
