Automating timecard PDF → structured data (OCR + PDFVector + n8n)
Hi everyone 👋I’m building a SaaS where users currently upload an Excel file that is manually created from daily worker timecard PDFs.
I’ve attached:
  • A sample timecard PDF (hard to read, scanned, inconsistent field names)
  • The final Excel output I need
Goal
Allow users to upload the PDF directly and automatically extract, per worker:
  • Date, Name
  • Time In
  • Lunch In / Out
  • Dinner In / Out
  • Wrap Time
  • Position
  • Department
Challenges
  • Poor OCR quality
  • Field names vary across PDFs
  • Semi-structured tables
  • High accuracy required (payroll data)
Plan
  • Use n8n for orchestration
  • Use PDFVector for PDF parsing / structured extraction
  • Add post-processing to normalize fields
Questions
  1. Is PDFVector reliable for row-level timecard extraction, or better as a helper only?
  2. Best OCR + extraction approach for scanned timecards?
  3. How would you design this pipeline for reliability at scale?
Appreciate any guidance or real-world experience 🙏
