Return the search value

I hope you are fine. I have asked this question twice before, but the answers were not suitable for me. I don't want to do this with Power Query. I want to search all 10064 words in column j in each of the cells in the column. And the result will be exactly the same words and written in column B facing each cell A. .

The values of column A are hypothetical. In reality, the column has about 40,000 cells. And if the results include several words in each cell of column B, put them in one cell and put a comma between each word. Please write the formula for me. Thank you

I use Excel 365.
