I was hoping to be able to use this to move between cells, columns and rows in a Google sheet, as well as adding text into cells, but it seems cells are not clickable elements? At least no number is lighted for cells when I use voice command "Click", only other parts of the sheet
Sadly it is not possible because google sheets doesn't implement the cells as regular input text that is the default way to do it when building a web application.
In order to support voice commands for Google Sheets a custom module can be implemented.
Thanks for trying the extension
