Shopify Product CSV Preflight Checker

Check your Shopify product CSV before it checks your patience.

Upload a product CSV and get a browser-only preflight report for duplicate SKUs, variant weirdness, missing prices, image gaps, SEO fields, and cleanup issues before Shopify gets anywhere near it.

Upload a Shopify product CSV

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.

What this checker does / does not do

StoreOpsCheck is a preflight checker. Shopify is still the final boss.

Does

  • Checks Shopify product CSV structure.
  • Groups rows by handle.
  • Detects variant option conflicts.
  • Checks prices, SKUs, missing fields, SEO/content, and cleanup issues.
  • Exports a local issue report when you ask for it.

Does not

  • Upload your CSV.
  • Import products.
  • Call the Shopify API.
  • Validate live image URLs.
  • Guarantee Shopify import success.
  • Fix the CSV for you.

What it checks

Import risk, data mess, and cleanup work.

  • Missing handles, titles, prices, and required-ish Shopify product CSV fields.
  • Duplicate non-empty SKUs and duplicate variant option combinations.
  • Inconsistent option names under the same handle.
  • Missing descriptions, SEO titles, SEO descriptions, and image alt text.
  • Whitespace, invisible characters, tag spacing, image URL spaces, and suspicious HTML.

Important nuance

Repeated handles are normal.

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.

Use this before imports, migrations, and bulk updates

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.
