Error 5000 — Data format problem

What this means

Amazon couldn't parse your product data. The file violates Amazon's XML Schema Definition (XSD) — wrong structure, invalid tags, or malformed content.

Why this happens

Generated XML doesn't validate against Amazon's XSD. Often hand-built feed exports that miss required wrapping elements, or schema-version mismatches.

How to fix it

  1. Validate your XML against Amazon's XSD schema files (downloadable from Seller Central).
  2. Use Amazon-provided feed templates rather than building XML from scratch.
  3. Check for unescaped special characters (& without &) that break XML parsing.
  4. Verify schema version matches the marketplace you're submitting to.
