CSV

CSV (Comma-Separated Values) is a simple format for storing tabular data in plain text. Each row is a data record, and columns are separated by commas (or other delimiters).

Technical Details

CSV files represent data in a flat table structure. The first row typically contains column headers, and each subsequent row contains values. Fields containing commas, newlines, or quotes may be enclosed in double quotes.

Advantages

  • Simple format that's easy to create and parse
  • Universal support across spreadsheet applications
  • Efficient storage for tabular data
  • Human-readable and editable in text editors

Limitations

  • No support for nested data structures
  • No standardized way to represent data types
  • Special characters may require escaping
  • No built-in support for formulas or calculations
NDJSON

NDJSON (Newline Delimited JSON) is a format where each line is a valid JSON object, making it easier to process large datasets sequentially.

Technical Details

Each line in an NDJSON file is a complete, self-contained JSON object ended by a newline character. This allows for streaming processing without loading the entire file into memory.

Advantages

  • Streaming-friendly for large datasets
  • Easy to append new records
  • Each record can be processed independently
  • Simpler to parse than JSON arrays for large datasets

Limitations

  • No support for cross-record references
  • Less widely supported than standard JSON
  • Each line must be a complete JSON object
  • Not suitable for deeply nested relationships
