Supporting Custom Shopify Business Applications with Google Sheets and GraphQL

Google Sheets is often treated as a place to export data, build reports, or make a quick list. But it is so much more than that: it is an accessible app-prototyping platform for building highly functional custom business-process and automation solutions.

With Google Sheets, Apps Script, and Shopify’s Admin GraphQL API, a spreadsheet can become a purpose-built operational application: one tailored to how a specific business manages products, data quality, inventory, merchandising, reporting, or approvals.

I built the Universal Shopify GraphQL Google Sheets Connector to make that kind of application easier to create.

The idea

The connector provides a reusable foundation for Google Sheets tools that need to read data from Shopify, apply business logic in a spreadsheet, and optionally send approved updates back to Shopify.

Instead of rebuilding Shopify authentication, GraphQL request handling, pagination, response flattening, and mutation logic for every new tool, a developer can build on a shared connector.

That means the Sheet can focus on the business process it is meant to support.

Example: a Shopify metadata quality-control application

One of the first applications I plan to build with this connector will automatically pull product data from Shopify into a Google Sheet and compare each product’s metadata against standardized table definitions.

The application can:

1. Pull product, variant, metafield, and other Shopify data into working tabs.

2. Compare those values against approved metadata standards maintained in reference tables.

3. Flag missing, invalid, inconsistent, or outdated values.

4. Give a user a clear place to review proposed corrections.

5. Send validated updates back to Shopify through GraphQL mutations.

In that workflow, the Google Sheet is not just an export. It is the application interface for data quality review, decision-making, validation, and controlled automation.

Problems it helps solve

This approach is useful wherever a business has a repeatable Shopify process but doesn't need—or doesn't yet want—a fully custom web application.

Examples include:

• Product metadata validation and correction.

• Bulk catalog cleanup projects.

• Product-title, tag, vendor, status, or metafield management.

• Merchandising review tools for collections and seasonal updates.

• Inventory or catalog reconciliation against external business data.

• Shopify reporting tools tailored to a team’s actual workflow.

• Approval-driven bulk updates, where spreadsheet users review proposed changes before they are sent to Shopify.

How the connector works

The system has three parts:

1. A Shopify custom app creates a store-specific Admin API access token.

2. A client-specific Apps Script proxy stores the token centrally and controls which approved Sheets applications can use it.

3. Downstream Google Sheets applications use the shared ShopifyGraphQL library to make requests through that proxy.

A typical request can be as simple as:

var response = ShopifyGraphQL.request(
  'query { products(first: 50) { nodes { id title handle } } }'
);

The library can then flatten Shopify’s nested GraphQL response into spreadsheet-friendly rows and columns.

From spreadsheet rows to Shopify updates

The connector also supports the reverse direction.

A Sheets application can read header-based rows, map selected columns into Shopify mutation payloads, validate the data, and run a dry run before sending live changes. This supports safer workflows where people can inspect proposed changes before production data is updated.

For example, a metadata-quality application could identify a product with an incorrect value, calculate the approved replacement from a standards table, write that proposed update into an editable review column, and only mutate Shopify after the row passes validation.

A reusable Shopify connection layer

The credential proxy is designed to act as a shared Shopify gateway for a client’s Google Workspace.

That allows multiple custom Sheets applications to reuse the same centrally managed Shopify connection:

Metadata Quality App
Catalog Manager
Reporting Tool
Inventory Utility
        ↓
Shared ShopifyGraphQL Library
        ↓
Central Apps Script Proxy
        ↓
Shopify Admin GraphQL API

This keeps Shopify access tokens out of downstream spreadsheets, reduces duplicated setup work, and makes access easier to manage as new applications are added.

Google Sheets as the right interface

When deploying organization-specific tools, building a custom web application isn't always the right direction. Google Sheets is familiar, collaborative, inexpensive to use, and backed by a reliable platform that most teams already have in place. Just like Shopify, it allows you to focus on the application instead of having to invest in server management

It is also scalable enough for the operational workflows of almost all Shopify stores: catalog review, product maintenance, metadata validation, reporting, approvals, and controlled bulk updates. Like any platform, it has practical limits—especially for massive real-time workloads or extremely high-volume processing—but it is an excellent fit for the vast majority of Shopify business operations.

The connector helps turn that familiar interface into something more powerful: a practical platform for building Shopify-connected business applications that fit the way a team actually works.
