Hello!
The point is this.
There are about 20k products already uploaded.
BUT! some products are duplicated how do i detect duplicates? Is there an article property, for example, is it somehow possible through it?

For example: I have a product - Bed 1, and the second - Bed - 2 - in the article property the same value, how can I identify this?

The easiest way is to set up the form for displaying the lists of the infoblock element by adding the article number field there, and sorting by it. This is such a gear on the right side of the item list page.
