I did several Excel to App implementation for the reasons you mention and more. I'd like to better understand the architecture of your proposal to consider it for my future projects. Does it run real Excel instance under the hood? Or is there a full emulation/interception going on? Can you cope with several linked excel spreadsheets at the same time ? Can you handle custom DLL loading/extending? Or perhaps, are you willing to share a whitepaper/architectural outline?

I'm using the Open Office Calc engine under the hood for Excel formula emulation. I extend that with my own implementation of the Excel4 API's xlcall32.dll, so that XLLs can invoke the Excel4 API. I also emulate Excel's built in RTD client, so that XLLs that supply an RTD server can push real time data into a sheet. Feel free to download the install kit [1], or email me on ssbeta@spreadserve.com for more detailed discussion. Thanks for the interest!

And yes, SpreadServe can cope with linked spreadsheets by means of websockets. Which means sheets can be daisy chained into a real time calc graph. This youtube video [1] demonstrates. [1] https://www.youtube.com/watch?v=MmPPMsOCmqA&t=10s https://www.youtube.com/watch?v=MmPPMsOCmqA&t=10s
