Shopify to Square CSV converter for market inventory

This tool is built for small Shopify store owners who sell at markets, pop-ups, craft fairs, and in-person events using Square Terminal. Before the market starts, export your Shopify products or inventory and turn it into a Square-ready import file. After the market ends, export your Square item or inventory file and turn it into a Shopify inventory update file.

Before the market

Use Shopify as the main store record. Convert Shopify product names, variants, SKUs, prices, and stock counts into a Square import CSV.

After the market

Use Square as the latest face-to-face sales record. Convert remaining Square stock back into a Shopify inventory CSV.

Built for safer imports

The app checks missing SKUs, duplicate SKUs, blank quantities, and risky rows before you download the final CSV.

How the market-day inventory workflow works

  • Export products or inventory from Shopify before the event.
  • Convert the file into a Square import CSV and load it into Square.
  • Sell in person using Square Terminal during the market.
  • Export Square inventory after the market ends.
  • Convert the Square export into a Shopify inventory update CSV.

1. Choose the task

Pick where you are in the market workflow.

2. Upload your file

Upload the Shopify product or inventory export you want to load into Square before the market.

Recommended after market: Shopify reference export

When converting Square to Shopify, add the latest Shopify product export so the app can fill Shopify handles and variant options accurately.

3. Review quality before upload

The app checks the transfer so the user can catch issues before uploading to Shopify or Square.

Upload a file, then click Convert and Review.
