Hey fellow Gophers! 
I released an OnlyOffice NLP solver. This didn’t exist in OnlyOffice before and was only available in MS Excel and LibreOffice.
So why am I posting this here in a Go forum?
You guessed it! I used Go compiled to WASM to create this. Sure, there’s a layer of fancy JS to get the data from the spreadsheet to the plugin, but the heavy lifting 
is done concurrently in Go, which makes it so fast.
Furthermore, cross-compiling enabled me to also work natively with a different build path and do all the testing and development just like for a normal Go app.
Still missing are side conditions, and I hope I can implement them before the end of the year.
A gentle call to action for you:
To develop this further, I would love to receive some example spreadsheets from people who work with spreadsheets a lot and have faced NLP problems in the past—maybe some finance guys or engineers. Examples that show real-world problems. Maybe people who needed to stick with Excel only because of the solver. Do you know someone?
I will test the examples and refine the plugin in terms of performance and fitting quality.
