Push Google Sheets price changes to Shopify with a sanity guard
Compares a pricing spreadsheet against live Shopify prices twice a day and pushes the differences, but holds any change larger than 25% for a human to confirm.
A twice-daily schedule reads the pricing sheet and the live Shopify catalogue. A Code node builds the diff in one pass: it indexes every variant's current price, drops rows whose variant id is unknown or whose price is unchanged or invalid, and computes the percentage move for the rest — so an unedited sheet produces no writes at all. An IF then applies the guard: moves within 25% go to the Shopify update, and anything larger is held and posted to Slack with both prices and the percentage, because a 90% drop is far more likely to be a decimal-point slip than a decision. The Shopify node is the only one in the workflow that writes to the store, and prices are sent as strings because the API rejects numbers. Only after Shopify confirms does an appendOrUpdate stamp lastPushed back into the sheet, so the sheet reflects what is live rather than what was intended. Failures route to an error rail on Discord.
Key benefits
- ✓Merchandising happens in a spreadsheet, where it can be reviewed, and still reaches the store
- ✓A 25% guard stops a decimal-point typo from going live unattended
- ✓Held changes are reported with both prices, so a deliberate big move can be confirmed rather than lost
- ✓The comparison is against live Shopify prices, so a manual edit in Shopify is not silently reverted
- ✓The sheet is stamped only after Shopify confirms, so it never claims a price that is not live
Use cases
- →Stores running sales or seasonal repricing across many variants
- →Merchandising teams who plan prices in a sheet and re-key them by hand
- →Agencies managing pricing for client stores with an audit trail
- →Anyone who has ever shipped a price with the decimal point in the wrong place
Integrations

What's inside (10 nodes)
A look at the node types this workflow uses. No purchase required — full parameters and credentials are yours after you buy.
From download to running in 3 steps
- 1Import. In n8n, open Workflows → menu → “Import from File” and pick the downloaded JSON.
- 2Connect. Add your own credentials on the app nodes - n8n highlights exactly which ones need them.
- 3Activate. Run it once to test, then toggle Active. The automation is live.
What you'll learn
Architect levelThe deepest tier - sub-workflow delegation, state snapshots, and full observability.
- •Moving data between Google Sheets, Shopify and Slack in a single run
- •Adding retries and an explicit error path to external calls
- •Testing against pinned sample data before connecting anything real
Every node carries its own documentation on the canvas, plus notes explaining why the architecture was built this way, a credential setup guide, troubleshooting, and three practice exercises. Sample data comes pinned to the trigger, so you can hit Execute and watch data flow before connecting a single account.
Common questions
What exactly do I get?
The complete, ready-to-import n8n workflow as a JSON file, delivered instantly after payment. Import it into your own n8n (cloud or self-hosted), add your credentials, and it runs.
How do I import it into n8n?
In n8n, open Workflows, click the three-dot menu, choose “Import from File”, and select the downloaded JSON. Then connect your own app credentials on the highlighted nodes.
Do I need anything else for it to work?
You need your own n8n instance and accounts/credentials for the apps this workflow connects to (Google Sheets, Shopify, Slack, Discord). No coding is required.
What if it doesn't work for me?
If the file is faulty, won't import, or isn't as described, contact us within 7 days and we'll fix it or refund you - see our refund policy.
Can I modify or resell it?
You can freely adapt and use it in your own or your clients' projects. Reselling or redistributing the template file itself is not permitted.
