Batch-update fields in PDF templates using Python
Project brief
A small command-line utility for PDFs that share one layout. It should take replacement dates, document numbers and names from a JSON or CSV file, process an input folder, and save separate output files.
The important part is keeping the surrounding typography and artwork intact. Use Python 3 with PyMuPDF or another library you can justify. Log missing fields and unreadable files instead of silently skipping them. This is for authorised template updates; sample PDFs and replacement values will be agreed before work begins.
Deliverables & acceptance
What you'll deliver
- Script, requirements.txt, README and results from two sample PDFs.
What the result must meet
- Configured fields change correctly in both test files; other text, images and layout remain unchanged.
- Originals are untouched; an unmatched field produces a clear warning.
