Answer 1

Generally the cached value will be written with the cell, so you can just read that (no need to evaluate)

Taking this formula cell as an example:

  <c r="B10">
    <f>SUM(B1:B9)</f>
    <v>4995</v>
  </c>

You read the f value to get the formula itself, or just read the v value to see what the evaluation of the formula was when excel last touched the file. No need to evaluate!
