Variant Grams
Flag decimal values, unit text, and nonstandard weight headers so you can keep Shopify import weight values numeric and predictable.
Shopify CSV weight check
Check Shopify product weight fields before CSV import.
Use this browser-side checker before retrying a Shopify product CSV when weight values do not update, Variant Grams is ignored, or the file mixes Variant Weight, Weight Unit, and shipping fields.
Requires Shipping
Catch physical variants where a weight exists but Requires Shipping is blank, false, or mapped inconsistently.
Matching variants
Review handles, option values, SKUs, and field mapping before using overwrite import on existing Shopify products.
Why Shopify CSV weight imports fail
Many CSV files mix supplier weight columns with Shopify export headers. Shopify product imports are safest when the row matches Shopify's own export shape, Variant Grams contains a whole-number gram value, and variant identity still matches the product being updated.
Need a cleanup pass after the report?
Run the free checker first. If the Issues CSV shows repeated weight, shipping, or variant-matching problems, use the pricing page to request a small manual cleanup quote.
What to export
Download an Issues CSV, field mapping file, and review rows so the exact row and column can be fixed before another import attempt.
What it does not do
It does not upload your CSV, connect to Shopify, fetch product data, or import anything into your store.
Best fit
Shopify merchants, catalog assistants, and migration freelancers cleaning product CSVs with weight or shipping-field problems.
