Use the matrix when the validation target is a set of variants rather than one canonical sample.
How to Use This Matrix

Coverage

  • Covers clean imports, multiline records, alternate delimiters, BOM behavior, and malformed rows.
  • Includes real 10MB to 250MB CSV files when transfer size and row-count volume matter as much as parser correctness.
  • Designed for spreadsheet upload flows, ETL staging, and CSV parser regression suites.
  • Pairs single-fixture downloads with the CSV import pack for bulk setup.
