I made a few plugins for the Tri city hospital in California. They had hundreds or thousands of documents un-organized. I made a PHP script to scan all the documents in separate locations, then I had WordPress create pages for each document. It would assign categories to the documents and add text that would allow the pages to display the file content on the page using a PDF viewer plugin. The sections are all password protected so only staff could view them. I also made a script that would allow people to modify cell content similar to an Excel sheet, but it used PHP as the base application script. I used jQuery and PHP to accomplish this.
