In the past, I have created a component to pass and retrieve values to/from excel using the excel libraries. The good thing is that once you have your workbook in memory and modify a cell (let's call it the origin cell) all the other cells with formulas that take this origin cell value are automatically refreshed.
Is this possible in OpenXml?
As far as I see, apparently this doesn't happen in OpenXml because the excel engine is not really executed in the background, OpenXml is just a group of classes to serialize, deserialize, read etc xml files right?
You can then work with live XML data in Excel. In Excel, open the Data tab and choose From Other Sources -> From Microsoft Query. Choose the XML DSN. Select the option to use Query Wizard to create/edit queries.
Use the Open command from within Excel to open an XML data file — and then select As an XML table in the Open XML dialog box.
Follow the below steps: Open the Excel application> Open the Task Manager> Right-click on Excel in Processes tab> Open file lication> It will take you to the location where Excel.exe is present.
That's correct, Office Open XML SDK is just a set of libraries to read/write XML files. It does not have any functionality for performing calculations.
You can specify that Excel should recalculate everything upon load by setting the following attribute, but if you need to read the new values in code (prior to re-opening in Excel) this won't help.
<workbook>
<calcPr fullCalcOnLoad="1"/>
</workbook>
Or in code with the Office Open XML SDK..
using (var doc = SpreadsheetDocument.Open(path, false))
{
doc.WorkbookPart.Workbook.CalculationProperties.FullCalculationOnLoad = true;
.
.
.
}
