HiI'm looking at using Office Web Apps with SharePoint 2013 to make some spreadsheets shareable.I want multiple users to be able edit the spreadshset simultaneously which seems very doable but the spreadsheet uses some quite major addins written with ExcelDNA - has anyone tried porting addins (either XLL or automation) to the Office Web Apps?Herr KartoffelKopf

@Govert is on Wilmott and is the creator of ExcelDNA. Maybe he is around.

Or you could post on the exceldna forumhttps://groups.google.com/forum/#!forum/exceldna

It essentially provides a cut down version of each office app which is integrated through a SharePoint Server with associated Office Web App server farms. I am looking specifically at Excel - the UI components are mostly common across Office products using XML similar to the Office UI xml. Specific to Excel is the User defined function (UDF) which is so expertly handled by ExcelDNA on the desktop client. In the OWA world these UDFs can be replicated on the server.OWA Server UDFsHas anyone here tried using these - I'm sure there are a number of pitfalls and limitations to discover the hard way.This looks like a great unifying technology, working in Office for Windows, Mac and Tablet but as always the big question is - is it there yet, can it be used as a full strength desktop Excel replacement/partner or is it still just an interesting but not yet usable proof of concept?Herr KartoffelKopf
