CSV Sample Files

Comma-Separated Values (.csv) files encode tabular data in a simple text-based format where each row is a record and commas (or other delimiters) separate fields. Ubiquitous in spreadsheets, databases, and ETL pipelines, CSV’s human-readable structure can hide edge cases like embedded delimiters, quoted fields, or multiline entries. Use sample .csv files to exercise parser resilience, header recognition, alternative delimiters (semicolon, tab), and streaming import in low-memory environments.
