In certain cases you may want to force Excel to re-calculate formulas when the workbook is opened.
Consider the following example:
- </p>
-
+ </p>
<p>
Open Excel and create a new workbook. On the first sheet set A1=1, B1=1, C1=A1+B1.
Excel automatically calculates formulas and the value in C1 is 2. So far so good.

Now open workbook2.xls in Excel and the value in C1 is still 2 while you expected 3. Wrong? No!
The point is that Excel caches previously calculated results and you need to trigger recalculation to updated them.
It is not an issue when you are creating new workbooks from scratch, but important to remember when you are modifing
existing workbooks with formulas. This can be done in two ways:

SXSSF.</p>
-
<p>If you are using POI 3.13 final or newer, formula evaluation is possible with SXSSF,
but with some caveats.</p>
-
<p>The biggest restriction is that, since evaluating a cell needs that cell in memory
and any others it depends on, only pure-function formulas and formulas referencing
nearby cells can be evaluated with SXSSF. If a formula references a cell that hasn't
yet been written, or one which has already been flushed to disk, then it won't be
possible to evaluate it.</p>
-
<p>Because of this, a call to <em>wb.getCreationHelper().createFormulaEvaluator().evaluateAll();</em>
will very rarely work on SXSSF, as it's very rare that all the cells wil be available
and in memory at any time! Instead, it is suggested to evaluate formula cells just
after writing them, or shortly after when cells they depend on are added. Just make
sure that all cells needing or needed for evaluation are inside the window.</p>
