Free Shopify CSV tool
Shopify variant image grouping checker.
Check whether your Shopify product CSV is ready to show the right image group when a customer selects a color or variant. Find option mismatches, missing image alt text, missing variant images, and image order problems before editing theme code.
Built for merchants debugging variant image switching, color-specific galleries, and product pages where selecting Black should show all black product images.
CSV preflight
Check variant image groups before theme edits
Paste your Shopify product CSV. The checker reads up to 750 rows and looks for common fields such as Handle, Option1 Name, Option1 Value, Image Src, Image Alt Text, and Variant Image.
Use cases
What this catches before Shopify theme work
These checks help separate CSV data problems from theme problems before you start editing Liquid or adding a variant image app.
Alt text missing color names
Many themes group images by image alt text. The checker flags images whose alt text does not include a variant option value.
Missing variant image fields
Shopify can attach one representative image to a variant. Blank variant image fields make native switching less reliable.
Image order problems
If images for the same color are split into separate groups, order-based gallery snippets can show the wrong media.
Option order drift
Mixed Color/Size ordering across rows can confuse variant logic and theme assumptions.
No recognized image columns
The checker tells you when the CSV has options but no product image or variant image fields to inspect.
FAQ
Shopify variant image switching
Can Shopify show a separate image gallery for each variant color?
Shopify can attach one image to a variant, but multi-image galleries per selected color usually depend on theme behavior, custom code, image order, image alt text, or consistent option values.
Why does selecting a Shopify variant only change one image?
A variant image field normally points to one image. Showing all black images when Black is selected often requires a theme that groups images by alt text, color value, or image order.
What CSV fields matter for variant image grouping?
The important fields are Handle, option names and values such as Color and Size, Image Src or Product image URL, Image Alt Text, and Variant Image or Variant Image URL.
Does this checker edit my Shopify theme?
No. It checks whether the CSV data is ready for variant image grouping. If the CSV is clean but the gallery still does not switch, the next step is theme configuration or theme code.
Should image alt text include the color name?
Many Shopify themes and snippets use image alt text to group color images. Including the exact option value, such as Black or Natural, makes that approach more reliable.
