Drop your Shopify product CSV here, or choose a file.
On iPhone or iPad, tap Choose CSV file and pick it from Files.
Your CSV stays in your browser. Nothing is uploaded, stored, imported, or sent to Shopify.
StoreOpsCheck is a preflight checker. Shopify is still the final boss.
What it checks
Important nuance
Shopify product CSVs can repeat a handle across variant rows. StoreOpsCheck does not flag repeated handles by itself, because repeated handles are how Shopify represents variants.
It flags trouble when rows under the same handle have suspicious variant structure, duplicate option combinations, or conflicting product-level data.
StoreOpsCheck is a preflight checker, not a Shopify importer and not a guarantee that Shopify will accept every row. Shopify’s importer is still the final boss. Keep a backup before bulk updates and test risky imports on a small file first.
The point is simple: catch the obvious danger before the file becomes tomorrow’s emergency.
