Document AI: OCR to Structured Data is a hands-on course in turning Thai and English invoices, forms and contracts into validated JSON with OCR and vision LLMs, backed by a human review step. It suits Python developers and automation teams who handle large volumes of documents, and you leave with a working extraction pipeline to adapt for your organisation.
Every organisation has documents that someone re-keys every day: invoices, tax invoices, receipts, application forms and contracts, often arriving as scanned PDFs or phone photos. Traditional OCR struggles with Thai and has no idea which number is the net total, while the latest AI models read documents far better but, used without checks, can return wrong figures or details the model simply made up, a risk that accounting and contract work cannot accept.
This course shows learners how to build a Document AI system that turns Thai and English documents into validated JSON. Learners prepare files and images and compare three approaches: an open OCR model such as Typhoon OCR, a cloud service such as Azure Document Intelligence, and vision LLMs such as Gemini and OpenAI models. They then force the output into a schema with structured output and Pydantic, check it against business rules, route uncertain documents to human reviewers, measure accuracy and cost, and assemble an automated pipeline with FastAPI and n8n. It closes with a capstone that extracts data from the learner's own document type. (2 days, 6 hours per day, 12 hours in total, Intermediate level.)
Course Details
The course runs for 2 days, 6 hours per day (12 hours in total, 09:00-16:00), as lectures with a lab in every section, using a set of sample documents that contain no real data. Intermediate level. It builds on RAG & Knowledge Base, which focuses on finding answers in documents, and shifts the goal to extracting fields from Thai invoices, forms and contracts as validated JSON that can be loaded into
other systems. Learners compare Typhoon OCR, Azure Document Intelligence and vision LLMs with real measurements. Learners use their own or company API accounts, which are billed by usage (some services offer a free tier or trial credit), and run open models on Google Colab or a cloud GPU paid for by the learner. Learners take home a lab guide, Python code for every lab, the sample documents with ground truth, and a sample n8n workflow.

Many organisations want staff to ask questions of their databases in plain language instead of waiting for the data team to write SQL every time. Today's LLMs write SQL far better than before, but once they are connected to a real database the same problems…
