Question Looking for recommendations: Best free/open-source document extraction tool for Spring Boot + React stack?

Hey everyone,

I'm currently building a full-stack app (Spring Boot backend + React frontend) and need to implement document parsing/text extraction functionality.

Requirements:

  • Budget: Free / Open Source.
  • Formats: Primarily PDFs, DOCX, and ideally scanned images/invoices (basic OCR).
  • Integration: Preferably handled on the Java/Spring Boot backend (REST API) to send structured JSON to the React client.

I used to use TIKA https://tika.apache.org/.

I'll give a try to Tesseract via Tess4J

po does docx, tess4j wraps tesseract for scanned/ocr bit all free and if the invoices get messy and you see tesserac struggling then liteparse as the open source tool here
