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.

Duplicate handles are not always wrong because Shopify variants share the parent product handle. This route separates normal variant groups from suspicious repeated product rows that need merchant review.

Import blockers

Common causes this scan checks

  • Blank handles are generated inconsistently from product titles.
  • Two unrelated products use the same handle after a bulk edit.
  • Variant rows are split away from their parent product rows.
  • Handles contain spaces, uppercase characters, or unsupported punctuation.

Workflow

How to use the cleaned CSV

  1. Scan the CSV and review handle groups instead of single rows only.
  2. Auto-fix blank or malformed handles when the title is clear.
  3. Manually decide whether suspicious duplicate groups are variants or separate products.
  4. Keep variant rows together before splitting or importing the file.

Auto-fix policy

What the export can safely change

  • Generates blank handles from clear product titles.
  • Lowercases handles and replaces spaces with hyphens.
  • Removes unsupported handle characters when the result is unambiguous.
  • Flags duplicate groups for review without merging products automatically.

FAQ

Shopify CSV questions

Are duplicate handles always wrong in Shopify CSV files?

No. Variant rows normally share a handle. The risk is when unrelated products accidentally share the same handle.

Can the tool merge duplicate products?

No. Merging products is a merchant decision. The tool points out suspicious groups so you can choose the correct structure.

What makes a handle valid?

A practical Shopify handle should be URL-friendly, lowercase, and avoid spaces or unsupported characters.
