What JSON structure is expected?
An array of objects, where all objects have the same keys — those keys become column headers.
How are nested objects handled?
Nested properties are flattened using dot notation keys (e.g. address.city).
What about arrays within JSON?
Array properties are typically serialised as comma-separated strings in the CSV.
Is the conversion bidirectional?
Yes — both JSON to CSV and CSV to JSON in the same tool.
Does it preserve data types?
In JSON output, numbers and booleans are preserved as their correct types.
