How to extract site information into a convenient table?

Question

big data

There is a website, for example, with a list of goods on several pages. Each product has a picture and a short description and a link to a detailed description. It is required to get a picture, a field from a short description and a field from a detailed description and put it all in a convenient table. This table should have filtering, sorting, adding your own fields.
The task occurs very often when choosing goods in online stores, searching for topics on forums without built-in advanced search engines, and so on.
Requirement for the tool: - the
ability to use it for free
- does not require knowledge of other languages ​​/ technologies
- must work with complex sites on java script, with authorization
This tool is needed in order to solve the problem of choosing goods / programs / services in a large offer

Answer 1

I don’t know about the free ones, but the Content Downloader
program is completely suitable for your tasks. It can do all of the above and even more.

Answer 2

I met links to such a solution , but I didn’t use it myself (for my tasks it’s easier to write it myself).

Answer 3

Start by understanding that you are not describing a tool, but a service (application or infrastructure). Divide this "something" already into tools. And then think about what you can find in a paid / free form, and what is more profitable to order to develop.
In this form, as described, you definitely won’t get a solution (both parsing, and adding to the spherical database, and filters, and simply solving the client’s problem).

Answer 4

I have not seen such tools. I recently made a similar program for a toaster.
The program downloads the page toster.ru/q/ID, then parses the necessary data and enters it into the database. Then I opened the database in the database viewer.
There and selection of the necessary data, and sorting.
If I understand correctly, you need to copy products from another site to your site.
I can try to help if you give a link to the site. Although I can not promise anything, because there may be problems with the java script.
