Product feed validation checks every row of your catalog export for missing data, duplicates, pricing errors and SEO weaknesses before it reaches Shopify, WooCommerce or a marketplace like Google Merchant Center.
Low-quality feeds get products disapproved, suppressed in search, or shown with incorrect information — directly costing conversions and ad spend efficiency.
Keep handles unique and lowercase, fill every Variant SKU, and write unique titles and descriptions for each product — avoid copy-pasted manufacturer text.
Ensure Regular Price is always numeric, Categories are assigned, and every simple/variable product has a unique SKU before exporting.
Google requires accurate GTIN/brand pairs where applicable, a valid availability value, and image links that resolve directly to an image file.
Duplicate SKUs confuse inventory systems and can cause marketplaces to merge or reject listings, hiding genuinely unique products from search.
A correct GTIN links your listing to the manufacturer's catalog data, improving trust signals and eligibility for rich shopping results.
Use a clean, high-resolution image on a plain background, keep ALT text descriptive, and avoid overlaid text or logos where possible.
Missing prices, blank titles, reused handles, and broken image links are consistently the most common issues found in real-world exports.
Before migrating platforms, validate SKUs, handles and prices first — these are the fields most likely to break redirects and order history.
No. Your CSV is read and validated entirely in your browser using JavaScript. It is never transmitted anywhere.
Shopify CSV exports, WooCommerce CSV exports, Google Merchant Center feeds, and generic custom CSVs are all auto-detected.
Up to the limit configured in Settings (100MB by default). Large files are processed in chunks to keep your browser responsive.
It is a 0–100 weighted score based on critical errors, warnings, duplicates and SEO issues found across your catalog.
Critical issues (like a missing price or duplicate SKU) can cause a product to be rejected outright. Warnings affect quality and discoverability but usually will not block a listing.
Auto Fix Mode can repair common formatting issues — extra spaces, malformed slugs/handles, inconsistent capitalization — and generates a new, repaired CSV copy. Your original file is never modified.
Never. Auto Fix always produces a separate, downloadable repaired copy alongside the original.
The validator compares SKU, Handle, GTIN, Slug and Title values across every row and flags exact-match repeats.
Yes — the Export Report tab lets you export everything, or filter to only errors, only warnings, or only passed products.
No. Every check is deterministic, rule-based validation — no external AI models or APIs are involved.
The engine is built to comfortably process feeds with 100,000+ products using chunked, memory-conscious processing.
