Is there any documentation or examples for what the server is expected to process and return to make persistence work with jspreadsheet? Its seems like we have to reverse engineer it.

i.e. - POST request to /jspreadheet/save

sometimes it sends:
data:{"insertRow":{"numOfRows":1,"rowNumber":6,"insertBefore":0,"data":[{"id":6,"data":["","","","",""]}]}}
or
data:{"deleteRow":{"rowNumber":4,"numOfRows":1,"data":[{"id":8,"row":4,"data":["","","","",""]}]}}'
or
data: {"updateData":[{"id":1,"row":"0","data":{"title":1234456}}]}
or
data:{"resetStyle":["B8","C8","D8","E8","F8","G8","B9","C9","D9","E9","F9","G9"]}
or
data:{"setStyle":{"B8":"color: initial","C8":"color: initial","D8":"color: initial","E8":"color: initial","F8":"color: initial","G8":"color: initial","B9":"color: initial","C9":"color: initial","D9":"color: initial","E9":"color: initial","F9":"color: initial","G9":"color: initial"}}

For return values:
{"success":1,"message":"Saved"}

Is that everything - are there any other commands/actions expected? what does it expect for failure?

Any examples to process this with .Net, C#?

Thanks
