PPTXToDocument

Convert PPTX files to documents your pipeline can query.

Key Features

• Converts PowerPoint presentation files to text documents for indexing.
• Configurable link format output: plain text, Markdown, or no links.
• Optional metadata attachment to resulting documents.

Configuration

1. Drag the PPTXToDocument component onto the canvas from the Component Library.
2. Click on the component to open the configuration panel.
3. Configure the component settings:
   • Set the Link Format to control how hyperlinks appear in the extracted text: none (default, text only), markdown (for [text](url)), or plain (for text (url)).
   • Set Store Full Path to control whether the full file path or just the file name is stored in document metadata.

Connections

PPTXToDocument accepts a list of file paths or ByteStream objects through its sources input. It outputs a list of Document objects.

It typically connects with:

• FileTypeRouter: receives PPTX files routed by MIME type.
• DocumentJoiner: sends converted documents to join with output from other converters before further processing.

Source Code

To check this component's source code, open pptx.py in the Haystack repository.

Using the Component in an Index

In this index, PPTXToDocument receives PPTX files from FileTypeRouter and sends them to DocumentJoiner.

Parameters

Inputs

Parameter	Type	Default	Description
sources	List[Union[str, Path, ByteStream]]		List of file paths or ByteStream objects to convert.
meta	Optional[Union[Dict[str, Any], List[Dict[str, Any]]]]	None	Optional metadata to attach to the Documents. This value can be either a list of dictionaries or a single dictionary. If it's a single dictionary, its content is added to the metadata of all produced Documents. If it's a list, the length of the list must match the number of sources, because the two lists will be zipped. If sources contains ByteStream objects, their meta will be added to the output Documents.

Outputs

Parameter	Type	Description
documents	List[Document]	Converted documents.

Init Parameters

These are the parameters you can configure in Pipeline Builder:

Parameter	Type	Default	Description
store_full_path	bool	False	If True, the full path of the file is stored in the metadata of the document. If False, only the file name is stored.
link_format	Literal['markdown', 'plain', 'none']	none	The format for link output. Options: "markdown" for [text](url), "plain" for text (url), "none" to extract only the text and ignore link addresses.

Run Method Parameters

These are the parameters you can configure for the component's run() method. This means you can pass these parameters at query time through the API, in Playground, or when running a job. For details, see Modify Pipeline Parameters at Query Time.

Parameter	Type	Default	Description
sources	List[Union[str, Path, ByteStream]]		List of file paths or ByteStream objects.
meta	Optional[Union[Dict[str, Any], List[Dict[str, Any]]]]	None	Optional metadata to attach to the Documents. This value can be either a list of dictionaries or a single dictionary. If it's a single dictionary, its content is added to the metadata of all produced Documents. If it's a list, the length of the list must match the number of sources, because the two lists will be zipped. If sources contains ByteStream objects, their meta will be added to the output Documents.
