techenthusiast167/NFOMINER — reverse-engineered prompt

Build me a simple self hosted web app called NFOMINER that lets someone paste in one or more document URLs and extract any hidden metadata from them. It should work with PDFs, Word files, Excel files, older Office files, and images.

The main screen should be easy to use, with a URL box, a file type choice if needed, an extract button, and a clean results page that shows things like author, created date, modified date, last modified by, software used, company, keywords, EXIF details, camera info, and GPS coordinates when they exist.

Please include bulk analysis so I can check multiple links at once, and let me download the results as CSV or JSON. Also add a simple REST API so another tool can submit a URL and get the metadata back. Use Python and Flask, keep it easy to run locally, and include clear setup and usage instructions. Look up current docs online if you need to.
