Automatic Update Of Cell Text Based On Item Number (also Text)?

I have a column C with different text in cells (item's title). Column D - relevant description for each of the items. 100+ rows.

Now, unfortunately, often a spreadsheet with items is updated with many new items. So I get a new spreadsheet with old and new items mixed. I need, somehow, to import descriptions of the old items (Column D of the old spreadsheet) to the new spreadsheet from old spreadsheet. So I want excel to look for old items in column A of the new spreadsheet and, once found, insert a description in the column B from old spreadsheet.
