Rowmoss

Rowmoss helps small Shopify store owners prepare occasional supplier files for new products. It converts one CSV into a Shopify product CSV containing one default variant per product, with draft status. You import the result yourself; no store connection is needed.
Upload UTF-8 or Windows-1252 CSV, choose comma or semicolon separation, and confirm Title, SKU, Price and optional Barcode. Select dot-decimal or European prices explicitly. Existing SKU and barcode zeros are preserved; missing zeros cannot be recovered. 3 complete converted files per browser credential without registration, plus 3 per account; anonymous and account use together is capped at 6 free complete deliveries per network address in 30 days; up to 100 source product rows per free file, with all conversion features including supplier row tags, store comparison and the skipped-row list. Before a successful complete download, previews show 20 rows and 20 issues. A successful free download allows viewing all rows up to 100. Larger files or exhausted allowances show upgrade options.
Errors block export by default. Correct the source or explicitly select valid rows only, then inspect the skipped-row list. Identical valid rows are merged and counted; conflicting SKUs can be set to keep the first row. Images, size/color variants, inventory, store synchronization and existing-product updates are outside scope. Limits are 1 MiB, 2,000 data rows and 30 columns.
