Contact
Email valmontmarketing@gmail.com with your question. For faster troubleshooting, identify which of the three tools you used, the error message and a description of what you expected.
Do not include real supplier CSV attachments, customer information, private access tokens, financial account details or Shopify credentials in an initial support request. You can describe the problem with synthetic data; files remain on your device when using the free tools.
Common questions
Why does the tool show a warning when my CSV seems fine?
Warnings identify situations that may require review; a repeated SKU is not automatically a rejected Shopify import. Review the CSV troubleshooting library and compare against Shopify's current official product import requirements.
Can I recover an import that changed my Shopify store?
SellerFile Studio does not interact with your Shopify store and does not keep a copy of uploaded files. Restore from your own store exports and backups or obtain authorized store support. Our current tools cannot undo a live product import.
How can I try your tools before using real seller data?
Download the synthetic CSV practice files and run them through a tool. The files contain example products rather than customer information.
How do I subscribe or request a refund?
Paid plans are not available yet. No customer charges or subscriptions exist through SellerFile Studio today. Read our planned pricing and billing and refund status for accurate information.
