CSV Tools for Shopify Merchants and Multi-Channel Sellers
Bulk catalog edits, inventory syncs across platforms, and margin calculations are exactly the kind of repetitive spreadsheet work that eats a merchant's week. These tools work directly on your standard Shopify, Amazon, and eBay CSV exports, no store connection or app subscription required.
Core Tool
A Suggested Workflow
Run the Bulk Product Editor and Profit Margin Calculator inside Shopify Tools first to clean pricing and confirm margins, then push the same export through Logical Dedupe or Fuzzy Join to reconcile SKUs across Amazon and eBay before re-uploading to Shopify. Use Outliers to catch anomalous prices or quantities before they go live, and Group By to break performance down by product category or channel.
Once you're ready to push changes back, export with CSV to XLSX and use Shopify's native CSV import (or a bulk import app) to apply them to your store.
