Amazon lookup guides

Practical documentation for using the tool accurately, interpreting available fields, and understanding caching and product-data limitations.

Find an Amazon ASIN

Find the 10-character ASIN on a product page or in a supported product URL.

Distinguish Amazon's catalog identifier from a seller-managed SKU before using the lookup.

Use supported /dp/, /gp/product/, and /gp/aw/d/ URLs from the 18-site allowlist.

Download the actual UTF-8 CSV and import its 14 columns into Excel without losing Unicode.

Learn what each normalized product field means and when optional values can be absent.

Locate the ten-character identifier after a supported product-path segment.

Avoid using a UPC or EAN as ASIN input and understand when a barcode may appear in public attributes.

Understand book identifier boundaries without promising ISBN-13 conversion.

Import the downloaded one-row CSV into Google Sheets while preserving nested JSON cells.

Choose among the three views of the same normalized result without another lookup.

Interpret null, empty, and unavailable fields without inventing values or forcing a refresh.

Understand cached responses, fetched timestamps, and why results are not guaranteed real-time.

Use the ASIN in the URL path while respecting the tool's single-product variation limits.

Copy or open available image links while recognizing that link access is not a reuse license.

Preserve Japanese, Arabic, accents, arrays, and grouped attributes across exports.

Read a downloaded ASINtoJSON file locally with Python's json module; this is not a public API workflow.
