Hi, I can build a tool in vb.net to read your excel file, add column and fill with data from persons pdf file.
In the past I worked with open source libraries as openxml (to read and write excel files) and itexthsharp to read data from pdf files.
The tool can import the excel file to see on screen rows and run the process to get pdf info, later save into excel append column with pdf data, you can set the input file, output file and set pdf folder location, or run a console type program to process the excel file and pdfs file in the same folder where do you run the program.
Check my portfolio, a lot of windows desktop applications, please send me a sample files to show you a demo without obligation.
