I will extract data from invoices, forms and pdfs with ocr and ai
About this Gig
Still copying data from invoices, receipts or forms by hand?
I build AI pipelines that read your documents and return clean, structured data (JSON, CSV or Excel), even from scans and photos.
How it works:
- OCR reads the text, including from low-quality scans
- An LLM extracts the exact fields you need: totals, dates, line items, names
- Validation rules flag missing or suspicious values for review
Why work with me:
- Top 6 of 269 teams, ICPR 2026, OCR on low-resolution images
- Top 1 of 1,060 teams, Zalo AI Challenge 2025 (computer vision)
- I build LLM and RAG systems, so the extraction step is accurate and explainable
What I can process:
- Invoices, receipts, purchase orders
- Forms, contracts, ID-style documents (with your consent)
- Mixed batches of PDFs and images
You receive the extraction script or API, a sample output on your files, and documentation.
Send me 3 to 5 sample documents and the fields you need. I will confirm accuracy on your real data before you order.
FAQ
Which documents can you process?
Invoices, receipts, purchase orders, forms and most business PDFs, including scans and phone photos. Send a sample and I will confirm.
How accurate is it?
It depends on scan quality and layout. I test on your real files first and report field-level accuracy before you commit to a larger package.
Which output formats do you support?
JSON, CSV, Excel, or direct insertion into a database or Google Sheet on request.
Is my data safe?
Your files are used only for your project and deleted after delivery on request. I can also run everything with open-source models so no data goes to third-party APIs.
Do I need an OpenAI or other API key?
Only if you choose a hosted LLM. Otherwise I can use open-source models that run on your own machine.
