Data files
In the Test Runner, choose a data file to run once per row. It can be a CSV file with a header row (RFC 4180 quoting, Windows line endings and a byte order mark are all fine) or a JSON list of objects, up to 10,000 rows.


Each column becomes a {{variable}} for that iteration, and scripts can read the row as api.iterationData.
A row’s values rank just below values set by scripts, and above the environment and the collection.
