Practical guide

JSON vs CSV vs Markdown for Amazon data

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

Practical details

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

JSON keeps native nested values, CSV provides one spreadsheet row with nested JSON cells, and Markdown emphasizes readable notes. All three are created from the same in-memory result without another lookup.

ASINtoJSON handles one product at a time. It does not provide bulk lookup, a public developer API, review text, live price or inventory, historical monitoring, sales estimates, or a complete variation graph.

Use this page

  1. Choose JSON for structured programs, CSV for one-row spreadsheets, or Markdown for readable notes.
  2. Switch the result tab without running the lookup again.
  3. Download the selected representation of the same normalized object.

Field and freshness notes

  • Results can be cached and are not guaranteed to be real-time.
  • Unavailable source fields are shown as not provided; currency identifies the marketplace currency and is not a price quote.

Working example

The fixed snapshot on the multiple-image example page demonstrates the current normalized fields and exact exporters. It was collected on October 4, 2026; it is a snapshot, not a live result.

Frequently asked questions

Does JSON vs CSV vs Markdown for Amazon data start a live lookup?

Using the form starts one single-product lookup, except the URL-to-ASIN parser, which runs locally without fetching product data.

Are results real-time?

Not necessarily. Successful results may be served from cache, and the displayed fetched time identifies when the product data was collected.
