SPECIMEN synthetic business documents with ground truth
Synthetic sample business documents for testing only, not real documents.
500 synthetic invoices, purchase orders, delivery notes, receipts and tables, each with the exact field values in JSON, for testing OCR and document-extraction pipelines.
Quickstart
from datasets import load_dataset
gt = load_dataset(
"json",
data_files="hf://datasets/markedet/specimen-business-docs/dataset/ground_truth.jsonl",
split="train",
)
print(gt[0]["file"], gt[0]["document_number"], gt[0]["total"])
Get the matching file:
from huggingface_hub import hf_hub_download
pdf = hf_hub_download("markedet/specimen-business-docs", "dataset/" + gt[0]["file"], repo_type="dataset")

Good to know
Abuse warning. Every file in this dataset is synthetic test data. Every page carries the diagonal watermark "SPECIMEN – SYNTHETIC TEST DATA – NOT A VALID DOCUMENT". All companies are recognisably fictional, all registration, VAT and account numbers are invalid by design and contain letters, and the currency code is XTS (the ISO 4217 code reserved for testing). These documents are not valid invoices, receipts or orders. Do not remove the watermark, do not alter them to look real, and do not present them to any person, business or authority as genuine. Doing so may be fraud. Use them only to test and evaluate document-processing software.
- Markings: the watermark is on every PDF page as text and as an image, drawn into every PNG, and in the
first and last rows and print header of every XLSX. Every file name starts with
SPECIMEN_. - Company names are made up and contain a marker such as Fictional, Fictitious, Specimen or Example.
Addresses use made-up streets and the postcode
SPEC-000. If a name resembles a real business, email novusops@mail.grokbot.com and it will be changed. - Not included: payslips, bank statements, identity documents, tax assessments, insurance policies, QR codes and payment codes.
- Layouts are simple and uniform and numbers are random, so scores here say little about real documents.
