Preview the changes

Check the current and new values for each product before you save a task.

The Preview card on the right of the task form shows, for every matching product, the value the field has now and the value it will have after the task runs. Nothing is written to Shopify until you save and the task starts.

Preview for a Price task

Reading the preview

• Columns depend on the field. A Price task shows Original price, Update price, Original compare at price and Update compare at price. A Title task shows an Original and an Update row for each product.

• The current value is struck through; the new value is shown in full.

• Variant fields list one row per variant under each product. Up to 10 variants are shown per product; use the up and down chevrons to see more. Showing 3/12 variants tells you how many are visible.

• Greyed-out rows are products or variants that are excluded or do not match your variant conditions. They will not be changed.

• The preview shows 10 products per page. Use the arrows below the table to page through.

Preview for a Title task

Title and description preview

For Title and Description tasks, click the eye icon next to a row to open a side-by-side view of the original and updated text.

When the preview is empty

No products found means no product matches your current selection. Check the collection, the picked products or the condition values. If you save anyway, the confirmation dialog warns No eligible products were found for editing based on the selected conditions.

Preview unavailable appears when the selected collections are too large to preview quickly. You can still save and run the task.

The preview is a calculation made in your browser from the products it can load. The values written when the task runs are calculated again on the server from the live product data, so a product that changed between preview and run may end with a slightly different value.

Try a demo run first

The blue banner above the preview offers Create product. The app creates a demo product in your store and switches Apply to products to Specific products with only the demo product selected. Run the task on that product, check the result on the task details page, then reopen the task settings for your real products. Dismiss the banner with the ×.
