Invoice Data Extraction PDF to JSON with OCR
China
Inglés
Sobre mí
I build invoice data extraction systems that turn PDFs — including scanned and phone-photo documents — into structured JSON and CSV. Every field carries the page number and verbatim quote it came from, so output is fully auditable. On identical scanned invoices, OCR off returned 0/22 fields; OCR on returned 22/22 correct, English and Chinese. Fast (about 6 seconds per digital PDF), batch-ready, and deployable as a REST endpoint your system can call. I share a live demo before any order so you can verify accuracy on your own documents first.
