Clean and Normalize Scraped Data for Shopify Import

What is E-Commerce Data Normalization?

Cleaning and normalizing scraped data for Shopify import is the systematic process of sanitizing raw catalog exports—removing broken HTML tags, standardizing currency formats, converting variant options into uniform capitalization, and eliminating duplicate whitespace—to ensure seamless, error-free ingestion into Shopify.

Raw scraped data often contains inconsistent vendor naming, unclosed HTML divs, or malformed prices that cause Shopify's CSV importer to reject rows.

1. Sanitize HTML Descriptions

Remove incompatible JavaScript snippets, inline iframe styles, and WordPress-specific shortcodes (e.g. [vc_row]) while preserving essential formatting tags like

• , and .

  2. Standardize Price Formats

  Strip currency symbols ($, €, £) and comma separators, converting raw strings like $1,249.99 USD into pure numerical decimal values (1249.99).

  3. Handle and Slug Standardization

  Ensure product handles contain only lowercase alphanumeric characters and hyphens (e.g., premium-leather-wallet) without special characters or accented letters.

  4. Variant Attribute Normalization

  Standardize option values so that "Large", "large", and "L" are unified under a single consistent option name across all product variants.

  5. Validate Public Image Links

  Verify that all image URLs are active, HTTPS-secured, and directly accessible by Shopify's background image crawler.
