Shopify Preflight Tools: Preview risky Shopify CSV changes before importing

Hi Product Hunt — I built Shopify Preflight Tools after repeatedly seeing CSV imports, theme updates and migration files reviewed with spreadsheets and manual spot checks. The suite contains five small offline tools: Product CSV Change Preview, Customer CSV Change Preview, Theme Update Change Preview, Migration Integrity Preflight and Payout Reconciliation Preflight. Files stay in the browser. The reports describe candidate changes and limitations; they do not connect to a store, modify data or promise that Shopify will behave a certain way. The public page uses synthetic examples, and each English ZIP is a one-time $19–$29 purchase. I am not affiliated with Shopify. I would especially value feedback from merchants or agencies who review these files before import: which manual decision is still missing from the reports?

What do you still check manually before a risky Shopify import?

I m curious how other merchants and agencies handle the last review before importing a product or customer CSV, updating a theme, or moving store data.

What are the two or three things you always check by hand, even if you already use a spreadsheet or an import app? And which mistake is hardest to spot until after the import?
