Private by default. Your Shopify product CSV data stays in this browser session. The export applies only safe deterministic changes and leaves manual-review items in the findings list.

Variant problems usually come from row grouping, option columns, and blank values rather than SKU fields alone. This page reviews the product structure that Shopify uses to create options and variants.

Import blockers

Common causes this scan checks

  • Option1 Name exists while Option1 Value is blank on a variant row.
  • Variant fields are present but option columns are missing.
  • Rows for the same product handle are not grouped together.
  • Single-variant products include partial option data from a previous template.

Workflow

How to use the cleaned CSV

  1. Scan option columns and grouped handles before editing SKUs or prices.
  2. Fill or remove incomplete option values based on the intended product setup.
  3. Keep every variant row for a handle together during cleanup and splitting.
  4. Retest a small product group before importing a large variant catalog.

Auto-fix policy

What the export can safely change

  • Fills safe single-variant defaults only when the product context is clear.
  • Trims option name and value whitespace.
  • Flags missing option columns before Shopify creates incomplete variants.
  • Keeps ambiguous variant decisions visible for manual review.

FAQ

Shopify CSV questions

Why do variant rows share the same handle?

Shopify groups variants under one product by handle, so shared handles are normal when option columns describe separate variants.

Is SKU enough to define a variant?

No. Shopify also needs the product handle and option columns to understand variant relationships.

Can the tool rebuild variant logic automatically?

Only in narrow single-variant cases. Most variant structure changes need a merchant decision.
