UTF-8 CSV, up to 15 MB. This build checks a documented subset and does not guarantee Shopify import acceptance.
Choose the matching Shopify import intent. Update checks identifiers, but this local tool cannot confirm which existing products Shopify will overwrite.

This build reads the file in browser memory. It has no upload endpoint, analytics collector, remote script, or AI API. To verify the boundary yourself, load the page, disconnect from the network, and run a check; the page's security policy blocks outbound connections.
Only unambiguous formatting changes are automatic. Product meaning, prices, variants, and formulas are never guessed.
Store state, image reachability, taxonomy validity, and overwrite consequences can require Shopify context and remain clearly unverified.
Practical CSV guides
Protect the source export, verify structure and grouping, and test a small subset before a consequential import.
Distinguish malformed CSV structure from visible punctuation and choose a safe re-export path.
Check current case-sensitive headings, required identifiers, and important dynamic-column exceptions.
Find repeated expressed option combinations without mistaking image-only continuation rows for variants.
