Shopify import preflight

Shopify CSV Validator

Check product CSV headers, handles, required values, SKUs and variant prices before uploading to Shopify.

Paste a Shopify product export or load the included failing sample.

Generate a schema

Infer a reusable schema from product columns.

After the tool runs

Shopify CSV Validator review guide

Use the tool above first. The supporting notes below help you interpret the result, fix the right issues in the right order, and choose the next DataDoctor tool without pushing SEO content above the actual task.

Best input

checking Shopify product CSV files before product import or catalog updates.

Output to keep

Keep a before/after import file plus a short list of rows changed for the target platform.

Next check

Run a generic CSV data quality check before final upload when the platform-specific checker passes.

What it checks

Shopify CSV Validator for real data work

Shopify CSV Validator focuses on the rules a real platform usually enforces: required headers, identity fields, duplicate keys and value formats.

  • Required Shopify headers
  • Duplicate product handles
  • Required field values
  • Variant prices and SKUs

Fix these first

Common errors to review before downstream work

Most failures come from small file issues that become expensive only after an API call, import job or spreadsheet cleanup. Fix blocking errors first, then re-run the same tool before moving forward.

  • Missing product handles
  • Non-numeric variant prices
  • Blank option values
  • Duplicate handles used for separate products

Recommended workflow

Run the check in this order

Use the report to fix platform-blocking issues first. After those pass, run broader CSV checks for blanks, type drift and suspicious rows before uploading.

  1. Step 1

    Paste the Shopify CSV

  2. Step 2

    Run the preflight

  3. Step 3

    Fix critical product and price issues

  4. Step 4

    Run a generic CSV quality check before upload

How to interpret a passing result

A pass means this specific preflight did not find the issues listed above. It is not a guarantee that the target system will accept every row, field, custom mapping or account-specific rule.

Platform presets catch common import rules, but account-specific mappings, custom fields and plan-specific limits can still reject rows.
