Shopify CSV prep · preview mode

Product spreadsheets are messy. Your Shopify import doesn’t have to be.

Fulus checks a supported product CSV, turns it into a Shopify product-import draft, and shows you what changed before you take it to your store.

A clear, reviewable draft

A smaller, safer step

Know what your file will become before you import it.

CSV imports are strict: headers, variants, prices, and row structure all need to line up. Fulus is designed to make those details visible before a file reaches your store.

01

Choose a supported CSV

Start with a simple product list or a flat variants sheet. You choose its currency and decimal style.

02

Check and review

Structural and data checks run before a preview appears. Review a sample and the conversion notes.

Import when you’re ready

The result is a draft CSV for new products. You download it and import it into Shopify yourself.

Clear boundaries

Built for a specific kind of product file.

Common questions

Will Fulus import products to my store?

No. It prepares a CSV draft for you to download and import using Shopify. It does not connect to or modify your store.

What happens if my file is unsupported?

The checker explains that it cannot continue. Unsupported or ambiguous files do not proceed to checkout, and Fulus does not offer manual file repair.

Can I use this for existing products?

No. The current workflow is for batches declared as new products. Existing-product updates are outside its scope.

Can I pay or buy this during the test?

No. Payment is currently disabled while the sample workflow is being tested. This page will be updated before a paid launch.
