How to programmatically evaluate Excel data validations using .NET?
What I would like to do:
1. Set a cell value.
2. Check with a program if cell values conform to data validation rules.
I could extract all the information needed to create a validation function, but I don't want to re-invent the wheel.
What I have in mind is along the lines of how [NPOI](https://github.com/nissl-lab/npoi) allows recalculating all formulas to reflect changes in a workbook:
```fsharp
let recalculateFormulas (workbook: XSSFWorkbook) =
let creationHelper = workbook.GetCreationHelper()
let formulaEvaluator = creationHelper.CreateFormulaEvaluator()
formulaEvaluator.EvaluateAll()
```
