How can we add Custom Add-In function in XlsIO?

In order to make XlsIO recognize unknown functions/add-ins like Bloomberg, we need to register them as custom add-in functions to enable XlsIO to use these functions as formulas. We can achieve this by using the following code:

C#

IAddInFunctions unknownFunctions = workbook.AddInFunctions;
unknownFunctions.Add( "blp" );
// Use Function
sheet.Range[ "A3" ].Formula = "blp(A1+\" CORP\",\"PX_LAST\")";

VB

Dim unknownFunctions As IAddInFunctions = workbook.AddInFunctions
unknownFunctions.Add("blp")
'Use Function
 sheet.Range("A3").Formula = "blp(A1+"" CORP"",""PX_LAST"")"

Here is a sample for your reference:

Take a moment to peruse the documentation where you can find basic Excel document processing options along with the features like import and export data, chart, formulas, conditional formatting, data validation, tables, pivot tables and, protect the Excel documents, and most importantly, the PDF, CSV and Image conversions with code examples.
