Format Details
JSONL
JSONL (JSON Lines, also known as NDJSON) stores one complete, valid JSON object per line in a plain-text file. This line-by-line structure makes it ideal for streaming large datasets, log files, and machine learning training data, since each record can be processed independently without loading the entire file into memory. JSONL is increasingly standard in data engineering, LLM training pipelines, and high-throughput logging systems.
HTML
HTML (HyperText Markup Language) is the standard markup language for creating web pages and web applications, maintained by the W3C. It defines the structure and content of documents using elements and tags, working alongside CSS for visual styling and JavaScript for interactivity. HTML is rendered by web browsers into the visual pages users see, and is the universal output format for documents published on the internet.
