Convert eurostat table of contents PDF to JSON

Question

Since there is no accessable API to the EUROSTAT data, each query should be created manually I found this table of contents And I want to extract it to a searchable JSON. In the file there are section titles, and each leaf has 3 links, But how can I connect links and titles and sections into a JSON?

I have this basic code:

PDFFile = open("table_of_contents_en.pdf",'rb')

PDF = PyPDF2.PdfFileReader(PDFFile)
pages = PDF.getNumPages()
key = '/Annots'
uri = '/URI'
ank = '/A'

for page in range(1,2):
    print("Current Page: {}".format(page))
    pageSliced = PDF.getPage(page)
    pageObject = pageSliced.getObject()
    if key in pageObject.keys():
        ann = pageObject[key]
        for a in ann:
            u = a.getObject()
            if uri in u[ank].keys():
                print(u[ank][uri])

And this for text:

pdfFileObj = open('table_of_contents_en.pdf', 'rb')
pdfReader = PyPDF2.PdfFileReader(pdfFileObj)
print(pdfReader.numPages)
pageObj = pdfReader.getPage(0)
print(pageObj.extractText())
pdfFileObj.close()

and this for download zips:

for page in range(1,2):
    print("Current Page: {}".format(page))
    pageSliced = PDF.getPage(page)
    pageObject = pageSliced.getObject()
    if key in pageObject.keys():
        ann = pageObject[key]
        for a in ann:
            u = a.getObject()
            if uri in u[ank].keys():
                print(u[ank][uri])
            if str(u[ank].keys()).find(".tsv.gz") != -1 :
                url = str(u[ank].keys())
                r = requests.get(url, allow_redirects=True)
                print(str(str(str(u[ank].keys()).split("/")[-1]).split(".")[0])
                open(str(str(str(u[ank].keys()).split("/")[-1]).split(".")[0]), 'wb').write(r.content)

But how can I do this at the same time correctly, in some structured data?

Try like this, this won't be a JSON, but the list of files in a folder can be converted to, here is how to get the files:

import PyPDF2
import requests

PDFFile = open("table_of_contents_en.pdf",'rb')

PDF = PyPDF2.PdfFileReader(PDFFile)
pages = PDF.getNumPages()
key = '/Annots'
uri = '/URI'
ank = '/A'

for page in range(pages):
    print("Current Page: {}".format(page))
    pageSliced = PDF.getPage(page)
    pageObject = pageSliced.getObject()
    if key in pageObject.keys():
        ann = pageObject[key]
        for a in ann:
            u = a.getObject()
            # if uri in u[ank].keys():
            #   print(u[ank][uri])
            if str(u[ank][uri]).find(".tsv.gz") != -1 :
                url = str(u[ank][uri])
                try:
                    r = requests.get(url, allow_redirects=True)
                    print(str(str(str(url).split("/")[-1]).split(".")[0]))
                    open(str(str(url).split("/")[-1]), 'wb').write(r.content)
                except:
                    print("ERROR ON" + url)

Usage:

Download the table of contents file from Eurostat: http://ec.europa.eu/eurostat/estat-navtree-portlet-prod/BulkDownloadListing?sort=1&file=table_of_contents_en.pdf
run python3 the code above, edited with the file name, if it has changed.
extract with some tool the downloaded .gz files (suggestion: How to unzip gz file using Python )
delete the .gz files.
