title: How to match good cells in excel thanks year and column name between 2 file
body: <p>I have 2 file xlsx,  who are like that :</p>
  <p>Here it's my first file who contains all values :</p>
  <p><a href="https://i.stack.imgur.com/F5W88.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/F5W88.png" alt="file1" /></a></p>
  <p>And now I created myself my own file who is like that :</p>
  <pre><code>Year  turnover   effectif margin
  2021   2500      343      34
  2022   3000      433      23   
  </code></pre>
  <p>in my file 2, you can see that number correspond at the row and column of my file1,    but I did it without formula excel,  I try to create a formula in file2 with maybe index, equiv  who would match my year with name of column to recover the value in file 1</p>
