PUBLIC-SAMPLE DEMONSTRATION

Deliberately seeded example using Shopify official public sample content. Not customer data, paid work, blind detection or demand evidence. No Shopify import was performed.

messy_demo_input.csv: known formatting problems deliberately added.
cleaned_demo_output.csv: only those declared formatting problems repaired.
change_log.csv: changed items only: 61 headers, 16 Price cells and 4 serialization rules. Logical record numbers include header record 1.
exceptions_report.csv: two unverified out-of-scope warnings, not resolved errors.

Declared rules: semicolon to comma delimiter; one leading UTF-8 BOM removed; surrounding ASCII header spaces removed; one leading $ removed from agreed two-decimal Price strings; LF record endings and minimal quoting for the output delimiter. Re-quoting may change with the delimiter.

All 976 cleaned data cells equal the retained public source. Exact source headers, identifiers, variants, row order and 624 blanks are preserved. Continuation blanks are not filled. No product facts were inferred.

No comprehensive Shopify schema, business-data, completeness or live URL validation. Import acceptance and production readiness are not established. CSV is untyped; import identifiers as text when viewing in spreadsheet software.
