Generic File Metadata Reader

Generic File Metadata Reader is a Dify tool plugin for reading metadata from common document files.

It supports both direct single-file input and a no-URL archive workflow where one ZIP file contains multiple documents to inspect.

Features

• Extracts metadata from Office Open XML files: , , , , , and .
• Extracts common PDF info fields from files.
• Computes file size and SHA-256 checksum.
• Reads supported files inside a ZIP archive.
• Returns structured JSON plus workflow variables for downstream nodes.

Tools

Extract Metadata

Reads metadata from one Dify file variable directly.

Extract Metadata From Archive

Reads metadata from each supported document inside one ZIP archive. This is useful when a workflow needs to process multiple files without passing public file URLs between nodes.

Privacy

Files are processed inside the Dify plugin runtime. The plugin does not intentionally store file content or call third-party APIs.
