Summary
Unstructured Transform converts PDFs, DOCX, PPTX, HTML, images, and scanned pages into clean structured output.
Marketplace behavior
This updates the existing
langgenius/unstructuredMarketplace plugin. Once approved and merged, Dify's repository workflow packages and uploads version 0.0.10 to the Marketplace. Users will discover and install it from the existing Unstructured listing, then authenticate at runtime with their own Unstructured account and API key. No shared Unstructured credential is included in the plugin.Validation
