How to Convert JSON to CSV Correctly

JSON and CSV model data differently. JSON can contain nested objects and arrays, while CSV is fundamentally tabular. This guide explains what to check when converting between them.

Start with records

An array of similarly shaped JSON objects is the most natural source for CSV.

Flatten nested objects

A nested object needs a column naming strategy. Our converter uses dot-separated paths for nested object properties.

Review arrays

An array inside a record does not naturally map to one flat CSV cell. Inspect how the converter represents it and decide whether a separate table is more appropriate.

Check headers and types

CSV values are text-oriented. After conversion, spreadsheets or import systems may infer types differently, so validate dates, numbers, booleans, and identifiers.
