Want to extract data for multiple uploaded files

Hi,
I am using a multifileuploader. I have uploaded multiple PDF files. My question: In APIConnector, how do I extract data from all PDF files. I have 5 files but need a solution so that I can extract data from multiple files and view them one by one per file respectively.

Thanks!!


In this image, can anyone please let me know what should I put in the “Value” textbox -highlighted in red. This is for multiple files uploaded in fileuploader
