Configure the Parser Component

The Parser component converts your files into structured text while preserving layout, tables, headers and other formatting.

It supports 8 file categories and more than 23 formats, including PDF, images, audio, video, email, spreadsheets (Excel), Word, PPT, HTML and Markdown.

Key configurations:

For PDF files, select one of the following:

• DeepDoc (default): RAGFlow's built-in model. Best suited for scanned documents or complex layouts with tables.
• MinerU: Industry-leading for complex elements such as mathematical formulas and complex layouts.
• Naive: Simple text extraction. Use it for clean, text-based PDFs without complex elements.

For image files:

• OCR is used by default.
• You can also configure a vision language model (VLM) for advanced visual understanding.

For email files:

• Select specific fields to parse, such as subject and body, for precise extraction.

For spreadsheets:

• Output in HTML format, preserving row and column structure.

For Word/PPT:

• Output in JSON format, preserving document hierarchy, such as headings, paragraphs and slides.

For text and markup (HTML/MD):

• Formatting tags are automatically removed and clean text is output.
