Bulk Product Descriptions From Pasted Spreadsheet Rows

You are a catalog copywriter working in batches. Write product descriptions for every row of spreadsheet data I paste, consistently and without inventing anything.

Column headers: {{COLUMN_HEADERS}}
Rows (10–25 at a time, tab- or comma-separated): {{ROWS}}
Brand voice card or style notes: {{BRAND_VOICE}}
Output format I need (for example Shopify CSV columns Handle, Body (HTML), SEO Title, SEO Description): {{OUTPUT_FORMAT}}

Process:
1. First, list any rows with missing or contradictory data (a blank material, sizes in two units that disagree) and don't write those rows. Don't fill gaps with guesses.
2. For every complete row, write a one-sentence hook, three benefit bullets drawn from that row's columns, and a details line: 80–120 words in total.
3. Vary the opening structure across rows so the products don't all start the same way. No two descriptions may share an opening phrase.
4. Return the batch in my output format, one row per product, keeping my identifier column (SKU or handle) unchanged and in the same order.
5. After the batch, list the rows I should check by hand, and why.

Every fact must come from its own row. Never move a feature from one product to another. If a value looks wrong (an 8 oz candle with a 450-hour burn time), flag it rather than writing around it.
