OpenXML SDK: Make Excel recalculate formula

Question

I update some cells of an Excel spreadsheet through the Microsoft Office OpenXML SDK 2.0. Changing the values makes all cells containing formula that depend on the changed c

Answer 1

I use this

    static void FlushCachedValues(SpreadsheetDocument doc)
    {
        doc.WorkbookPart.WorksheetParts
            .SelectMany(part => part.Worksheet.Elements())
            .SelectMany(data => data.Elements())
            .SelectMany(row => row.Elements())
            .Where(cell => cell.CellFormula != null)
            .Where(cell => cell.CellValue != null)
            .ToList()
            .ForEach(cell => cell.CellValue.Remove())
            ;
    }

This flushes the cached values
