xlsx generation in nodejs, along with graphs
I have the same problem and I am looking for the solution as well. I have found https://www.npmjs.com/package/xlsx-chart but I don't know yet how to integrate data along with the chart because the plugin generate separate sheet for data and table.
Using https://www.npmjs.com/package/quiche you will get an URL with the image. I´ve tryed to integrated it in exceljs or to save it like an image but seems impossible
