How to programmatically validate a cell's value based on Excel data validation constraints?
- Which .NET project can programmatically validate a cell's value out of the box based on Excel data validation constraints?
- What I would like to do:
- 1. Set a cell value.
2. Check with a program if the cell value conforms to the data validation rules set for that cell.I could extract all the information needed to create a validation function, but I don't want to re-invent the wheel.---This question may be perceived as a duplicate of [Is there a way to programmatically evaluate Excel data validations using npoi in .NET?](https://stackoverflow.com/questions/74204029/is-there-a-way-to-programmatically-evaluate-excel-data-validations-using-npoi-in), but I tried to cast a wider net while also attempting to provide an answer.- [1]: https://learn.microsoft.com/en-us/office/open-xml/open-xml-sdk

- ```fsharp
- let recalculateFormulas (workbook: XSSFWorkbook) =
- let creationHelper = workbook.GetCreationHelper()
- let formulaEvaluator = creationHelper.CreateFormulaEvaluator()
- formulaEvaluator.EvaluateAll()
