Format Details
TSV
TSV (Tab-Separated Values) is a plain-text tabular data format that uses tab characters as column delimiters and newlines to separate rows, making it similar to CSV but avoiding issues when data values contain commas. It is well-supported by spreadsheet applications, relational databases, and scripting languages, and is commonly used for data exports from bioinformatics databases, genome browsers, and text-processing pipelines.
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.
