02 / IMPORT SAFETY GUIDE

Import safely, not blindly.

The highest-risk errors are often not invalid prices — they're files that change a product's variant structure.

01 / PREPARE

Export a fresh backup first

For existing Shopify products, keep a copy of the full original export. Don't sort variant and extra-image rows independently from their product handle.

02 / VERIFY

Check variant identity

When an update includes SKU or weight, preserve the matching option columns. Changing existing option values can replace variant IDs. The preflight flags common dependencies and duplicate option combinations.

03 / TEST

Import one product first

Shopify has separate product and inventory CSV formats. Use the correct one, test on a small subset, and confirm variant counts, images and inventory afterwards.

RELEVANT OFFICIAL DOCUMENTATION

Read Shopify's product CSV field reference ↗ and import safety notes ↗. Our preflight doesn't access your store and cannot verify that a file will import successfully, that image URLs actually resolve, or that existing variants match. It checks the CSV you give it.

03 / TRUST FIRST

Useful. Independent. Transparent.

01 / YOUR DATA
