## Overview The `MarkdownToDocument` component converts Markdown files into documents. You can use it in an indexing pipeline to index the contents of a Markdown file into a Document Store. It takes a list of file paths or [ByteStream](../../concepts/data-classes.mdx#bytestream) objects as input and outputs the converted result as a list of documents. Optionally, you can attach metadata to the documents through the `meta` input parameter. When you initialize the component, you can optionally turn off progress bars by setting `progress_bar` to `False`. If you want to convert the contents of tables into a single line, you can enable that through the `table_to_single_line` parameter. ## Usage You need to install `markdown-it-py` and `mdit_plain packages` to use the `MarkdownToDocument` component: ```shell pip install markdown-it-py mdit_plain ``` ### On its own ```python from haystack.components.converters import MarkdownToDocument converter = MarkdownToDocument() docs = converter.run(sources=Path("my_file.md")) ``` ### In a pipeline ```python from haystack import Pipeline from haystack.document_stores.in_memory import InMemoryDocumentStore from haystack.components.converters import MarkdownToDocument from haystack.components.preprocessors import DocumentCleaner from haystack.components.preprocessors import DocumentSplitter from haystack.components.writers import DocumentWriter document_store = InMemoryDocumentStore() pipeline = Pipeline() pipeline.add_component("converter", MarkdownToDocument()) pipeline.add_component("cleaner", DocumentCleaner()) pipeline.add_component( "splitter", DocumentSplitter(split_by="sentence", split_length=5), ) pipeline.add_component("writer", DocumentWriter(document_store=document_store)) pipeline.connect("converter", "cleaner") pipeline.connect("cleaner", "splitter") pipeline.connect("splitter", "writer") pipeline.run({"converter": {"sources": file_names}}) ``` ## Additional References :notebook: Tutorial: [Preprocessing Different File Types](https://haystack.deepset.ai/tutorials/30_file_type_preprocessing_index_pipeline)
