PPTXToDocument

Converts PPTX files to documents.

Basic Information

• Type: haystack.components.converters.pptx.PPTXToDocument
• Components it can connect with:
  • FileTypeRouter: PPTXToDocument can receive PPTX files from FileTypeRouter.
  • DocumentJoiner: PPTXToDocument can send converted documents to DocumentJoiner. This is useful if you have other converters in your pipeline and want to join their output with PPTXToDocument's output before sending it further down the pipeline.

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	Default	Description
documents	List[Document]		Converted documents

Overview

Use PPTXToDocument in your indexes to convert PPTX files to documents you can write into a document store.

Parameters

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.

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.
