What feed formats can I validate?

You can upload standard CSV and TSV product feeds with comma, tab, or pipe delimiters.

What errors does the validator detect?

Missing required attributes (id, title, price, link, image_link, availability), invalid GTINs, and currency syntax errors.

Is there a row limit?

You can validate up to 5,000 product rows directly in your browser.

Why do product feeds get rejected by Google Merchant Center and Meta?

The most common rejection causes include missing required attributes (like SKU or image link), price mismatches between the feed and your checkout page, invalid landing page URLs, non-standard stock values (e.g., using 'yes' instead of 'in_stock'), duplicate product identifiers across variants, and broken or non-HTTPS image links.

Does this tool guarantee Google Merchant Center approval?

No validator can offer guaranteed official approval. While our tool performs comprehensive structural, syntactic, duplicate, and hygiene checks matching Google and Meta specifications, actual merchant approval depends on real-time factors outside the feed file—including checkout tax/shipping configurations, business verification, merchant return policies, and landing page HTTP crawlability.

Is my product catalog data private when using this validator?

Yes, 100%. All feed processing, row parsing, column mapping, and rule audits run entirely within your web browser's JavaScript engine. Your raw catalog file is never uploaded to our servers or stored in memory unless you explicitly click 'Save Report' (which only saves the statistical issue summary, never your raw product records).

What is CSV Formula Injection and why does it matter for e-commerce feeds?

CSV Formula Injection (CWE-1236) occurs when product descriptions, titles, or promo codes begin with characters like '=', '+', '-', or '@'. If exported to CSV and opened in Microsoft Excel or Google Sheets, the spreadsheet may execute those values as formula macros, potentially executing commands or exfiltrating data. Silixen automatically neutralizes all exported CSV values with safe quote prefix escaping.

How does the column mapping feature work?

Different e-commerce platforms use different column headers—for example, Shopify uses 'Variant SKU' and 'Variant Price', while WooCommerce uses 'SKU' and 'Regular price', and Google uses 'id' and 'price'. Our auto-mapper identifies your platform headers automatically and allows you to adjust field assignments to match any custom feed layout.

Can this validator fix errors in my product feed automatically?

We provide an optional 'Export Cleaned Data' feature that trims whitespace, normalizes stock status values to standardized terms (like 'in_stock'), and strips illegal formatting. However, we never silently alter your data: proposed corrections are shown in a transparent preview and require your explicit review and approval before download.

What file size and row limits apply to the validator?

To ensure instantaneous client-side processing without freezing your browser tab, we support CSV files up to 10MB and up to 5,000 product rows in a single session. For larger multi-gigabyte feeds, we recommend validating in catalog batches or sample slices.

Merchant Technical Guide

Essential Standards for E-Commerce Catalog Feeds

Clean product feeds prevent disapproved shopping ads, increase organic product snippet eligibility, and ensure seamless synchronization between your store inventory and external channels.

Mandatoryid / sku

Unique Product Identifier

Every product and variant must have a stable, non-changing alphanumeric SKU. Reusing an ID across multiple distinct products causes overwrites and inventory reporting errors.

Mandatorytitle

Product Title

Clearly describe the item including brand, model, color, and size (up to 150 characters). Avoid promotional text like "FREE SHIPPING" or ALL CAPS shouting.

Mandatoryprice

Price & Currency

Must be a positive numeric amount accompanied by an ISO currency code (e.g. 29.99 USD). The feed price must match the landing page price exactly.

Mandatorylink

Landing Page URL

Direct HTTP/HTTPS link to the item detail page on your domain. Avoid redirect loops or links that land on category pages instead of the specific product.

Mandatoryimage_link

Main Image URL

High-resolution public HTTPS URL of the primary product photo (JPEG, PNG, or WebP). Watermarks, promotional badges, and placeholder graphics are prohibited on Google Shopping.

Mandatoryavailability

Stock Availability

Standardized values: in_stock, out_of_stock, preorder, or backorder. Non-standard values like "available" or "yes" trigger disapproval.

An e-commerce product feed is a structured data file (typically CSV, TSV, or XML) containing your product catalog's essential commercial attributes—such as SKU/ID, title, price, landing page URL, image link, availability, and brand. Marketing platforms like Google Shopping, Meta Commerce Manager, TikTok Shop, Pinterest, and affiliate networks ingest this feed to display dynamic shopping ads and sync inventory.
