[OFFER] Focused Shopify product CSV preflight — no store login

Hi everyone,

I’ve launched Catalog Lantern for merchants who want a second look at a product CSV before importing it into Shopify.

The service checks selected risks with CSV structure, prices, product status values, repeated SKUs, variant combinations and image URL syntax. The original file stays unchanged, and the result is a readable report showing which records need attention.

The current pilot covers one product-only UTF-8 CSV with up to 500 data records and 20 MiB, plus one rerun after corrections. It does not edit or import products, access a live store, validate custom apps or metafields, or guarantee that Shopify will accept a file.

Please do not send customer records, order data, passwords or API keys.

The free checklist and synthetic sample report are here:

If the checklist helps and you want the defined paid package, the page shows how to order.

I’m especially interested in hearing which part of a product CSV causes merchants the most uncertainty before import. Questions and feedback are welcome in the public thread.

Disclosure: I run Catalog Lantern. This is a new, tool-assisted service with a deliberately narrow scope.

Launch update: the full 500-record preflight is now $40 for the first three completed orders. The scope remains one product-only UTF-8 CSV up to 20 MiB, a report of selected risks, and one rerun. No store login, edits, import, custom-app or metafield checks, or guarantee of acceptance. Booking remains through the page linked above.

Correction to my earlier launch update: the founding-client price is now $20 for the first completed order, then it returns to $40. The scope remains one product-only UTF-8 CSV with up to 500 data records and 20 MiB, a report of selected risks, and one rerun. No store login, edits, import, custom-app or metafield checks, or guarantee of acceptance. Booking remains through the page linked above.
