24  ## Overview
25  
26  The `XLSXToDocument` component converts XLSX files into Haystack Documents with a CSV (default) or Markdown format. 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.
27  
28  To see the additional parameters that you can specify with the component initialization, check out the [API Reference](/reference/converters-api#xlsxtodocument).

30  ## Usage
31  
32  First, install the openpyxl and tabulate packages to start using this converter:
33  
34  ```shell
35  pip install pandas openpyxl
36  pip install tabulate
37  ```
38  
39  ### On its own
40  
41  ```python
42  from haystack.components.converters import XLSXToDocument
43  
44  converter = XLSXToDocument()
45  results = converter.run(
46      sources=["sample.xlsx"],
47      meta={"date_added": datetime.now().isoformat()},
48  )
49  documents = results["documents"]
50  print(documents[0].content)
51  ## ",A,B\n1,col_a,col_b\n2,1.5,test\n"
52  ```
53  
54  ### In a pipeline
55  
56  ```python
57  from haystack import Pipeline
58  from haystack.document_stores.in_memory import InMemoryDocumentStore
59  from haystack.components.converters import XLSXToDocument
60  from haystack.components.preprocessors import DocumentCleaner
61  from haystack.components.preprocessors import DocumentSplitter
62  from haystack.components.writers import DocumentWriter
63  
64  document_store = InMemoryDocumentStore()
65  
66  pipeline = Pipeline()
67  pipeline.add_component("converter", XLSXToDocument())
68  pipeline.add_component("cleaner", DocumentCleaner())
69  pipeline.add_component(
70      "splitter",
71      DocumentSplitter(split_by="sentence", split_length=5),
72  )
73  pipeline.add_component("writer", DocumentWriter(document_store=document_store))
74  pipeline.connect("converter", "cleaner")
75  pipeline.connect("cleaner", "splitter")
76  pipeline.connect("splitter", "writer")
77  
78  pipeline.run({"converter": {"sources": file_names}})
79  ```
