Where can one find API docs for the client-side viewer? (The same one that powers the viewer demo here) Or alternatively, unobfuscated code would be just as useful.
I understand the viewer is based on the x-spreadsheet library, but it seems to be heavily modified.
@nikitar
for the document please check Working with GridJs Client Side|Documentation
and run the demo from here
https://github.com/aspose-cells/Aspose.Cells-for-.NET/tree/master/Examples_GridJs
and you can get the latest js from
gridjs-spreadsheet - npm
feel free to contact us if you meet any issue
