An NDJSON file holds one JSON value per line, usually one record per line; it is the same format as JSON Lines.
A Parquet file is a columnar data table: each column is stored on its own, compressed and typed, so analytics tools can read only the columns they need. It is the common exchange format of data lakes, Spark, pandas and DuckDB.
