## 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}})
```
