?Frequently Asked Questions
JSON vs NDJSON - which should I use?
Use regular JSON for small datasets or when you need a single array. Use NDJSON (newline-delimited JSON) for large datasets or streaming processing - each line is a valid JSON object, making it easier to process incrementally.
Are nested schemas supported?
Yes! Parquet supports complex nested types (structs, arrays, maps), and this converter preserves that structure in the JSON output using nested objects and arrays.
