  <p>Open-Source Pre-Processing Tools for Unstructured Data</p>
</h2>

The `unstructured` library provides open-source components for ingesting and pre-processing images and text documents, such as PDFs, HTML, Word docs, and [many more](https://docs.unstructured.io/open-source/core-functionality/partitioning). The use cases of `unstructured` revolve around streamlining and optimizing the data processing workflow for LLMs. `unstructured` modular functions and connectors form a cohesive system that simplifies data ingestion and pre-processing, making it adaptable to different platforms and efficient in transforming unstructured data into structured outputs.

## Try the Unstructured Platform Product

Ready to move your data processing pipeline to production, and take advantage of advanced features? Check out [Unstructured Platform](https://unstructured.io/enterprise). In addition to better processing performance, take advantage of chunking, embedding, and image and table enrichment generation, all from a low code UI or an API. [Request a demo](https://unstructured.io/contact) from our sales team to learn more about how to get started.

## :eight_pointed_black_star: Quick Start

There are several ways to use the `unstructured` library:
* [Run the library in a container](https://github.com/Unstructured-IO/unstructured#run-the-library-in-a-container) or
* Install the library
    1. [Install from PyPI](https://github.com/Unstructured-IO/unstructured#installing-the-library)
    2. [Install for local development](https://github.com/Unstructured-IO/unstructured#installation-instructions-for-local-development)
* For installation with `conda` on Windows system, please refer to the [documentation](https://unstructured-io.github.io/unstructured/installing.html#installation-with-conda-on-windows)

### Run the library in a container

The following instructions are intended to help you get up and running using Docker to interact with `unstructured`.
See [here](https://docs.docker.com/get-docker/) if you don't already have docker installed on your machine.

NOTE: we build multi-platform images to support both x86_64 and Apple silicon hardware. `docker pull` should download the corresponding image for your architecture, but you can specify with `--platform` (e.g. `--platform linux/amd64`) if needed.

We build Docker images for all pushes to `main`. We tag each image with the corresponding short commit hash (e.g. `fbc7a69`) and the application version (e.g. `0.5.5-dev1`). We also tag the most recent image with `latest`. To leverage this, `docker pull` from our image repository.

```bash
docker pull downloads.unstructured.io/unstructured-io/unstructured:latest
```

Once pulled, you can create a container from this image and shell to it.

```bash
# create the container
docker run -dt --name unstructured downloads.unstructured.io/unstructured-io/unstructured:latest

# this will drop you into a bash shell where the Docker image is running
docker exec -it unstructured bash
```

You can also build your own Docker image. Note that the base image is `wolfi-base`, which is
updated regularly. If you are building the image locally, it is possible `docker-build` could
fail due to upstream changes in `wolfi-base`.

If you only plan on parsing one type of data you can speed up building the image by commenting out some
of the packages/requirements necessary for other data types. See Dockerfile to know which lines are necessary
for your use case.

```bash
make docker-build

# this will drop you into a bash shell where the Docker image is running
make docker-start-bash
```

Once in the running container, you can try things directly in Python interpreter's interactive mode.
```bash
# this will drop you into a python console so you can run the below partition functions
python3

>>> from unstructured.partition.pdf import partition_pdf
>>> elements = partition_pdf(filename="example-docs/layout-parser-paper-fast.pdf")

>>> from unstructured.partition.text import partition_text
>>> elements = partition_text(filename="example-docs/fake-text.txt")
```

### Installing the library
Use the following instructions to get up and running with `unstructured` and test your
installation.

- Install the Python SDK to support all document types with `pip install "unstructured[all-docs]"`
  - For plain text files, HTML, XML, JSON and Emails that do not require any extra dependencies, you can run `pip install unstructured`
  - To process other doc types, you can install the extras required for those documents, such as `pip install "unstructured[docx,pptx]"`
- Install the following system dependencies if they are not already available on your system.
  Depending on what document types you're parsing, you may not need all of these.
    - `libmagic-dev` (filetype detection)
    - `poppler-utils` (images and PDFs)
    - `tesseract-ocr` (images and PDFs, install `tesseract-lang` for additional language support)
    - `libreoffice` (MS Office docs)
    - `pandoc` is bundled automatically via the `pypandoc-binary` Python package (no system install needed)

- For suggestions on how to install on the Windows and to learn about dependencies for other features, see the
  installation documentation [here](https://unstructured-io.github.io/unstructured/installing.html).

At this point, you should be able to run the following code:

```python
from unstructured.partition.auto import partition

elements = partition(filename="example-docs/eml/fake-email.eml")
print("\n\n".join([str(el) for el in elements]))
```

### Installation Instructions for Local Development

The following instructions are intended to help you get up and running with `unstructured`
locally if you are planning to contribute to the project.

This project uses [uv](https://docs.astral.sh/uv/) for dependency management. Install it first:

```bash
# macOS / Linux
curl -LsSf https://astral.sh/uv/install.sh | sh
```

Then install all dependencies (base, extras, dev, test, and lint groups):

```bash
make install
```

This runs `uv sync --locked --all-extras --all-groups`, which creates a virtual environment
and installs everything in one step. No need to manually create or activate a virtualenv.

To install only specific document-type extras:

```bash
uv sync --extra pdf
uv sync --extra csv --extra docx
```

To update the lock file after changing dependencies in `pyproject.toml`:

```bash
make lock
```

* Optional:
  * To install extras for processing images and PDFs locally, run `uv sync --extra pdf --extra image`.
  * For processing image files, `tesseract` is required. See [here](https://tesseract-ocr.github.io/tessdoc/Installation.html) for installation instructions.
  * For processing PDF files, `tesseract` and `poppler` are required. The [pdf2image docs](https://pdf2image.readthedocs.io/en/latest/installation.html) have instructions on installing `poppler` across various platforms.

Additionally, if you're planning to contribute to `unstructured`, we provide you an optional `pre-commit` configuration
file to ensure your code matches the formatting and linting standards used in `unstructured`.
If you'd prefer not to have code changes auto-tidied before every commit, you can use  `make check` to see
whether any linting or formatting changes should be applied, and `make tidy` to apply them.

If using the optional `pre-commit`, you'll just need to install the hooks with `pre-commit install` since the
`pre-commit` package is installed as part of `make install` mentioned above. Finally, if you decided to use `pre-commit`
you can also uninstall the hooks with `pre-commit uninstall`.

In addition to develop in your local OS we also provide a helper to use docker providing a development environment:

```bash
make docker-start-dev
```

This starts a docker container with your local repo mounted to `/mnt/local_unstructured`. This docker image allows you to develop without worrying about your OS's compatibility with the repo and its dependencies.

### PDF Document Parsing Example
The following examples show how to get started with the `unstructured` library. The easiest way to parse a document in unstructured is to use the `partition` function. If you use `partition` function, `unstructured` will detect the file type and route it to the appropriate file-specific partitioning function. If you are using the `partition` function, you may need to install additional dependencies per doc type.
For example, to install docx dependencies you need to run `pip install "unstructured[docx]"`.
See our  [installation guide](https://docs.unstructured.io/open-source/installation/full-installation) for more details.

```python
from unstructured.partition.auto import partition

elements = partition("example-docs/layout-parser-paper.pdf")
```

Run `print("\n\n".join([str(el) for el in elements]))` to get a string representation of the
output, which looks like:

LayoutParser : A Uniﬁed Toolkit for Deep Learning Based Document Image Analysis

Zejiang Shen 1 ( (cid:0) ), Ruochen Zhang 2 , Melissa Dell 3 , Benjamin Charles Germain Lee 4 , Jacob Carlson 3 , and
Weining Li 5

Abstract. Recent advances in document image analysis (DIA) have been primarily driven by the application of neural
networks. Ideally, research outcomes could be easily deployed in production and extended for further investigation.
However, various factors like loosely organized codebases and sophisticated model conﬁgurations complicate the easy
reuse of important innovations by a wide audience. Though there have been ongoing eﬀorts to improve reusability and
simplify deep learning (DL) model development in disciplines like natural language processing and computer vision, none
of them are optimized for challenges in the domain of DIA. This represents a major gap in the existing toolkit, as DIA
is central to academic research across a wide range of disciplines in the social sciences and humanities. This paper
introduces LayoutParser, an open-source library for streamlining the usage of DL in DIA research and applications.
The core LayoutParser library comes with a set of simple and intuitive interfaces for applying and customizing DL models
for layout detection, character recognition, and many other document processing tasks. To promote extensibility,
LayoutParser also incorporates a community platform for sharing both pre-trained models and full document digitization
pipelines. We demonstrate that LayoutParser is helpful for both lightweight and large-scale digitization pipelines in
real-word use cases. The library is publicly available at https://layout-parser.github.io

Introduction

Deep Learning(DL)-based approaches are the state-of-the-art for a wide range of document image analysis (DIA) tasks
including document image classiﬁcation [11,
