Disclsoure Extractor is an open source repository to extract data from PDFs of judicial financial data It was built for use with Courtlistener.com.
It uses image processing and OCRing to extract data on financial records. Additional functionality estimates a judges' net worth from the disclosures.
Further development is intended and all contributors, corrections and additions are welcome.
Free Law Project built this to help extract out data from roughly 18k financial records. These records are available for a limited period from the US Government before they are destroyed. In an effort to review roughly 20 years of records we needed a method to extract out the information at a high degree of accuracy.
Below is an example output from Justice Alitos' abbreviated output from his 2011 disclosure, followed by the output in table format with calculations.
The main function process_financial_document accepts a url, filepath, or PDF as bytes.
from disclosure_extractor import (
process_financial_document,
print_results
)
output = process_financial_document(filepath)
returns:

This code was developed for financial disclosures released after 2007ish. In older documents reimbursements was consolidated into only two fields from the current five. This causes data to be incorrectly identified by sections.
Installing disclosure-extractor will be easy.
pip install disclosure-extractor
Or install the latest dev version from github
pip install git+https://github.com/freelawproject/disclosure-extractor.git@master
- Continue to improve output for older financial disclosures
Releasing a new version to PyPI is handled in a Github workflow.
Once a version is ready to be released, adjust the version number in the setup.py file and add tag the branch in the following format and push to github.
v*.*.*
The action will build and push to PyPI.
If you wish to create a new version manually, the process is:
Update version info in
setup.pyInstall the requirements in requirements_dev.txt
Set up a config file at ~/.pypirc
Generate a universal distribution that worksin py2 and py3 (see setup.cfg)
python setup.py sdist bdist_wheel
Upload the distributions
twine upload dist/* -r pypi (or pypitest) python setup.py sdist upload -r pypi
This repository is available under the permissive BSD license, making it easy and safe to incorporate in your own libraries.
