What is JSONLines?

JSONLines (or NDJSON - Newline Delimited JSON) is a convenient format for storing structured data that may be processed one record at a time. It consists of one valid JSON object per line, with each line separated by a newline character. This format is ideal for:

  • Log files that contain structured data
  • Stream processing of large datasets
  • Data exchange between systems where each line can be processed independently
  • Appending new records without loading the entire file
