QUESTION
My supervisor wants me to convert .pdf files to .txt files to be processed by a keyword extraction algorithm. The .pdf files are scanned court documents. She essentially wants a folder called court_document with subdirectories each named a 13-character case ID. I received about 500 .pdf files with file names "caseid_docketnumber_date_documentdescription.pdf", e.g. "1-20-cr-30164_d2_5_23_2020_complaint.pdf". She also wants each .txt file to be saved as "docketnumber_date_documentdescription.txt", e.g. "d2_5_23_2020_complaint.txt". The .pdf files are saved in my working directory court_document. The desired outcome is a root directory called court_document with 500 subdirectories each containing .txt files. I approached the problem as follows:

...ANSWER
Answered 2021-Aug-30 at 03:07Unfortunately a reprex will be to complex so here goes a description of how you can achive a structured df:
I am afraid you have to use pdftools::pdf_data() instead of pdftools::pdf_text().
This way you get a df for each page in a list. In these dfs you get a line for each word on the page and the exact location (plus extensions IRCC). With this at hands you can write a parser to accomplish your task... which will be a bit of work but this is the only way I know to solve this sort of problem.
update:I found a readr function that helps for your case, since we can assume a fixed lenght (nchar()) for the colum positions:
