## csv

### CSVToDocument

Converts CSV files to Documents.

By default, it uses UTF-8 encoding when converting files but
you can also set a custom encoding.
It can attach metadata to the resulting documents.

### Usage example

```python
from haystack.components.converters.csv import CSVToDocument
from datetime import datetime

converter = CSVToDocument()
results = converter.run(
    sources=["test/test_files/csv/sample_1.csv"], meta={"date_added": datetime.now().isoformat()}
)
documents = results["documents"]

print(documents[0].content)
# >>  'col1,col2\nrow1,row1\nrow2,row2\n'
```

#### __init__

```python
__init__(
    encoding: str = "utf-8",
    store_full_path: bool = False,
    *,
    conversion_mode: Literal["file", "row"] = "file",
    delimiter: str = ",",
    quotechar: str = '"'
) -> None
```

Creates a CSVToDocument component.

**Parameters:**

- **encoding** (<code>str</code>) – The encoding of the csv files to convert.
  If the encoding is specified in the metadata of a source ByteStream,
  it overrides this value.
- **store_full_path** (<code>bool</code>) – If True, the full path of the file is stored in the metadata of the document.
  If False, only the file name is stored.
- **conversion_mode** (<code>Literal['file', 'row']</code>) – - "file" (default): one Document per CSV file whose content is the raw CSV text.
- "row": convert each CSV row to its own Document (requires `content_column` in `run()`).
- **delimiter** (<code>str</code>) – CSV delimiter used when parsing in row mode (passed to `csv.DictReader`).
- **quotechar** (<code>str</code>) – CSV quote character used when parsing in row mode (passed to `csv.DictReader`).

#### run

```python
run(
    sources: list[str | Path | ByteStream],
    *,
    content_column: str | None = None,
    meta: dict[str, Any] | list[dict[str, Any]] | None = None
) -> dict[str, Any]
```

Converts CSV files to a Document (file mode) or to one Document per row (row mode).

**Parameters:**

- **sources** (<code>list\[str | Path | ByteStream\]</code>) – List of file paths or ByteStream objects.
- **content_column** (<code>str | None</code>) – **Required when** `conversion_mode="row"`.
  The column name whose values become `Document.content` for each row.
  The column must exist in the CSV header.
- **meta** (<code>dict\[str, Any\] | list\[dict\[str, Any\]\] | None</code>) – 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.

**Returns:**

- <code>dict\[str, Any\]</code> – A dictionary with the following keys:
- `documents`: Created documents

## image/document_to_image

### DocumentToImageContent

Converts documents sourced from PDF and image files into ImageContents.

This component processes a list of documents and extracts visual content from supported file formats, converting
them into ImageContents that can be used for multimodal AI tasks. It handles both direct image files and PDF
documents by extracting specific pages as images.

Documents are expected to have metadata containing:

- The `file_path_meta_field` key with a valid file path that exists when combined with `root_path`
- A supported image format (MIME type must be one of the supported image types)
- For PDF files, a `page_number` key specifying which page to extract

### Usage example

```python
from haystack import Document
from haystack.components.converters.image.document_to_image import DocumentToImageContent

converter = DocumentToImageContent(
    file_path_meta_field="file_path",
    root_path="test/test_files",
    detail="high",
    size=(800, 600)
)

documents = [
    Document(content="Optional description of apple.jpg", meta={"file_path": "images/apple.jpg"}),
    Document(
        content="Optional description of sample_pdf_1.pdf",
        meta={"file_path": "pdf/sample_pdf_1.pdf", "page_number": 1}
    )
]

result = converter.run(documents)
image_contents = result["image_contents"]
# [ImageContent(
#    base64_image='/9j/4A...', mime_type='image/jpeg', detail='high', meta={'file_path': 'images/apple.jpg'}
#  ),
#  ImageContent(
#    base64_image='/9j/4A...', mime_type='image/jpeg', detail='high',
#    meta={'file_path': 'pdf/sample_pdf_1.pdf', 'page_number': 1})
#  )]
```

#### __init__

```python
__init__(
    *,
    file_path_meta_field: str = "file_path",
    root_path: str | None = None,
    detail: Literal["auto", "high", "low"] | None = None,
    size: tuple[int, int] | None = None
) -> None
```

Initialize the DocumentToImageContent component.

**Parameters:**

- **file_path_meta_field** (<code>str</code>) – The metadata field in the Document that contains the file path to the image or PDF.
- **root_path** (<code>str | None</code>) – The root directory path where document files are located. If provided, file paths in
  document metadata will be resolved relative to this path. If None, file paths are treated as absolute paths.
- **detail** (<code>Literal['auto', 'high', 'low'] | None</code>) – Optional detail level of the image (only supported by OpenAI). Can be "auto", "high", or "low".
  This will be passed to the created ImageContent objects.
- **size** (<code>tuple\[int, int\] | None</code>) – If provided, resizes the image to fit within the specified dimensions (width, height) while
  maintaining aspect ratio. This reduces file size, memory usage, and processing time, which is beneficial
  when working with models that have resolution constraints or when transmitting images to remote services.

#### run

```python
run(documents: list[Document]) -> dict[str, list[ImageContent | None]]
```

Convert documents with image or PDF sources into ImageContent objects.

This method processes the input documents, extracting images from supported file formats and converting them
into ImageContent objects.

**Parameters:**

- **documents** (<code>list\[Document\]</code>) – A list of documents to process. Each document should have metadata containing at minimum
  a 'file_path_meta_field' key. PDF documents additionally require a 'page_number' key to specify which
  page to convert.

**Returns:**

- <code>dict\[str, list\[ImageContent | None\]\]</code> – Dictionary containing one key:
- "image_contents": ImageContents created from the processed documents. These contain base64-encoded image
  data and metadata. The order corresponds to order of input documents.

**Raises:**

- <code>ValueError</code> – If any document is missing the required metadata keys, has an invalid file path, or has an unsupported
  MIME type. The error message will specify which document and what information is missing or incorrect.

## image/file_to_document

### ImageFileToDocument

Converts image file references into empty Document objects with associated metadata.

This component is useful in pipelines where image file paths need to be wrapped in `Document` objects to be
processed by downstream components such as the `LLMDocumentContentExtractor` or the
`SentenceTransformersDocumentImageEmbedder` (available in the `sentence-transformers-haystack` integration).

It does **not** extract any content from the image files, instead it creates `Document` objects with `None` as
their content and attaches metadata such as file path and any user-provided values.

### Usage example

```python
from haystack.components.converters.image import ImageFileToDocument

converter = ImageFileToDocument()

sources = ["image.jpg", "another_image.png"]

result = converter.run(sources=sources)
documents = result["documents"]

print(documents)

# [Document(id=..., meta: {'file_path': 'image.jpg'}),
# Document(id=..., meta: {'file_path': 'another_image.png'})]
```

#### __init__

```python
__init__(*, store_full_path: bool = False) -> None
```

Initialize the ImageFileToDocument component.

**Parameters:**

- **store_full_path** (<code>bool</code>) – 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

```python
run(
    *,
    sources: list[str | Path | ByteStream],
    meta: dict[str, Any] | list[dict[str, Any]] | None = None
) -> dict[str, list[Document]]
```

Convert image files into empty Document objects with metadata.

This method accepts image file references (as file paths or ByteStreams) and creates `Document` objects
without content. These documents are enriched with metadata derived from the input source and optional
user-provided metadata.

**Parameters:**

- **sources** (<code>list\[str | Path | ByteStream\]</code>) – List of file paths or ByteStream objects to convert.
- **meta** (<code>dict\[str, Any\] | list\[dict\[str, Any\]\] | None</code>) – Optional metadata to attach to the documents.
  This value can be 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, its length must match the number of sources, as they are zipped together.
  For ByteStream objects, their `meta` is added to the output documents.

**Returns:**

- <code>dict\[str, list\[Document\]\]</code> – A dictionary containing:
- `documents`: A list of `Document` objects with empty content and associated metadata.

```

#### __init__

```python
__init__(
    jq_schema: str | None = None,
    content_key: str | None = None,
    extra_meta_fields: set[str] | Literal["*"] | None = None,
    store_full_path: bool = False,
) -> None
```

Creates a JSONConverter component.

An optional `jq_schema` can be provided to extract nested data in the JSON source files.
See the [official jq documentation](https://jqlang.github.io/jq/) for more info on the filters syntax.
If `jq_schema` is not set, whole JSON source files will be used to extract content.

Optionally, you can provide a `content_key` to specify which key in the extracted object must
be set as the document's content.

If both `jq_schema` and `content_key` are set, the component will search for the `content_key` in
the JSON object extracted by `jq_schema`. If the extracted data is not a JSON object, it will be skipped.

If only `jq_schema` is set, the extracted data must be a scalar value. If it's a JSON object or array,
it will be skipped.

If only `content_key` is set, the source JSON file must be a JSON object, else it will be skipped.

`extra_meta_fields` can either be set to a set of strings or a literal `"*"` string.
If it's a set of strings, it must specify fields in the extracted objects that must be set in
the extracted documents. If a field is not found, the meta value will be `None`.
If set to `"*"`, all fields that are not `content_key` found in the filtered JSON object will
be saved as metadata.

Initialization will fail if neither `jq_schema` nor `content_key` are set.

**Parameters:**

- **jq_schema** (<code>str | None</code>) – Optional jq filter string to extract content.
  If not specified, whole JSON object will be used to extract information.
- **content_key** (<code>str | None</code>) – Optional key to extract document content.
  If `jq_schema` is specified, the `content_key` will be extracted from that object.
- **extra_meta_fields** (<code>set\[str\] | Literal['\*'] | None</code>) – An optional set of meta keys to extract from the content.
  If `jq_schema` is specified, all keys will be extracted from that object.
- **store_full_path** (<code>bool</code>) – If True, the full path of the file is stored in the metadata of the document.
  If False, only the file name is stored.

#### to_dict

# >> 'This is a text from the PDF file.'
```

#### __init__

```python
__init__(
    line_overlap: float = 0.5,
    char_margin: float = 2.0,
    line_margin: float = 0.5,
    word_margin: float = 0.1,
    boxes_flow: float | None = 0.5,
    detect_vertical: bool = True,
    all_texts: bool = False,
    store_full_path: bool = False,
) -> None
```

Create a PDFMinerToDocument component.

**Parameters:**

- **line_overlap** (<code>float</code>) – This parameter determines whether two characters are considered to be on
  the same line based on the amount of overlap between them.
  The overlap is calculated relative to the minimum height of both characters.
- **char_margin** (<code>float</code>) – Determines whether two characters are part of the same line based on the distance between them.
  If the distance is less than the margin specified, the characters are considered to be on the same line.
  The margin is calculated relative to the width of the character.
- **word_margin** (<code>float</code>) – Determines whether two characters on the same line are part of the same word
  based on the distance between them. If the distance is greater than the margin specified,
  an intermediate space will be added between them to make the text more readable.
  The margin is calculated relative to the width of the character.
- **line_margin** (<code>float</code>) – This parameter determines whether two lines are part of the same paragraph based on
  the distance between them. If the distance is less than the margin specified,
  the lines are considered to be part of the same paragraph.
  The margin is calculated relative to the height of a line.
- **boxes_flow** (<code>float | None</code>) – This parameter determines the importance of horizontal and vertical position when
  determining the order of text boxes. A value between -1.0 and +1.0 can be set,
  with -1.0 indicating that only horizontal position matters and +1.0 indicating
  that only vertical position matters. Setting the value to 'None' will disable advanced
  layout analysis, and text boxes will be ordered based on the position of their bottom left corner.
- **detect_vertical** (<code>bool</code>) – This parameter determines whether vertical text should be considered during layout analysis.
- **all_texts** (<code>bool</code>) – If layout analysis should be performed on text in figures.
- **store_full_path** (<code>bool</code>) – If True, the full path of the file is stored in the metadata of the document.
  If False, only the file name is stored.

#### detect_undecoded_cid_characters

```python
detect_undecoded_cid_characters(text: str) -> dict[str, Any]
```

Look for character sequences of CID, i.e.: characters that haven't been properly decoded from their CID format.

This is useful to detect if the text extractor is not able to extract the text correctly, e.g. if the PDF uses
non-standard fonts.

A PDF font may include a ToUnicode map (mapping from character code to Unicode) to support operations like
searching strings or copy & paste in a PDF viewer. This map immediately provides the mapping the text extractor
needs. If that map is not available the text extractor cannot decode the CID characters and will return them
as is.

see: https://pdfminersix.readthedocs.io/en/latest/faq.html#why-are-there-cid-x-values-in-the-textual-output

**Parameters:**

- **text** (<code>str</code>) – The text to check for undecoded CID characters

  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.

- **link_format** (<code>Literal['markdown', 'plain', 'none']</code>) – The format for link output. Possible options:
- `"markdown"`: `[text](url)`
- `"plain"`: `text (url)`
- `"none"`: Only the text is extracted, link addresses are ignored.
- **store_full_path** (<code>bool</code>) – 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

```python
run(
    sources: list[str | Path | ByteStream],
    meta: dict[str, Any] | list[dict[str, Any]] | None = None,
) -> dict[str, list[Document]]
```

Converts a XLSX file to a Document.

**Parameters:**

- **sources** (<code>list\[str | Path | ByteStream\]</code>) – List of file paths or ByteStream objects.
- **meta** (<code>dict\[str, Any\] | list\[dict\[str, Any\]\] | None</code>) – 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.

**Returns:**

- <code>dict\[str, list\[Document\]\]</code> – A dictionary with the following keys:
- `documents`: Created documents
