Extract all the links of a website

Excel Facts

What is the last column in Excel?
Excel columns run from A to Z, AA to AZ, AAA to XFD. The last column is XFD.
The folder contains four files. Which file are you referring to?
The file to use is: links
In this file you need to insert the file code: Scraping_title
that will have to extract the name of the website and insert it in column "b" of sheet 2.
In sheet 1 of the link file it is necessary to insert the code of file 1 to extract all the links of each url.
Then I found another file which is: Regxp Emails2
This last file has the hidden code and it appeared to me when I debugged it following a macro error.
Which of the two macros (file 1 and Regxp Emails2 file) in your opinion extracts all the links more effectively and efficiently? You can use the better code of the two to do this.
The Regxp Emails2 file makes the example of extracting the link of the facebook page, instead I would like to extract in addition to this link to be inserted in sheet 2 of the links file (column d) also the other links that contain the word indicated in the column header of sheet 2 (from column d onwards).
For column c I will need the regex code that I already have and that I will have to use it the same way I use it to extract the email.

Thank you for your interview. I could ask you to insert it in the dropbox link file along with the other code with the creation of the buttons that activates each code. Then I noticed that activating the code there could be some problems with certificates that are asked that block the macro until I click on the "yes" of the mask that appears. Is it possible to automatically accept and save the data automatically and then restart the macro from the first raw line? Then I would like to learn how to insert the email extraction part included in that code.
