Open a path or s3:// / gs:// / az:// URI, or upload a file (streamed to a temp directory). The page shows a bounded sample, equivalent CLI lines, profile, frequency, filter, SQL (default LIMIT 500), export, convert --low-memory, validate, mask, and pipeline YAML export. Use undatum api serve for a read-only machine API.
