Shopify Products: Prepare product CSVs for Shopify import.

Built for the import problems that waste hours.

RowSift starts narrow: high-value cleanup before Shopify product imports and HubSpot contact imports, plus a generic cleaner for everyday CSV work.

Shopify

Product CSV repair

Normalize legacy headers, generate URL handles, clean prices, and flag rows that still need attention.

HubSpot

Contact hygiene

Normalize email and phone fields, surface invalid emails, and warn about duplicate contact identifiers.

Browser-first processing

The free tool reads and transforms CSV text in the browser. Your file does not need to be uploaded to our server.

Start free, upgrade when imports become a workflow.

The free cleaner works without an account. Pro adds an account-saved destination and subscription management. Pro costs $12 USD per month, renews automatically each month until canceled, and has no free trial. Applicable taxes are shown before payment; each payment is covered by the 30-day Refund Policy. Paddle checkout is currently unavailable while production setup and end-to-end testing are completed. Team features are planned and not available for purchase.

Frequently asked questions

Does RowSift upload my CSV?

The free cleaner in this version processes the CSV in your browser. The file does not need to be sent to a backend to clean and download it.

Can it make every Shopify CSV valid automatically?

It fixes common formatting problems and flags remaining blocking issues. Store-specific fields, product relationships, and business rules can still require review before import.

Why are duplicate HubSpot emails flagged?

Email is commonly used as the unique identifier for contacts. Duplicate identifiers can update the same contact or create confusing import behavior, so the tool surfaces them before import.

What will the paid plan add?

Pro currently saves your preferred cleaning destination across signed-in devices. Advanced mappings, reusable rules, team sharing and API delivery remain planned and are not included as available features.
