Hello there,

In my application I'm building an Excel document row by row and stream each row when it's done. One cell has rich formatting - some words have specific colours. I think I'm doing the right thing but in the Excel document the cell has the value [Object object].
I guess this is the toString() of the object instead of the correct rendering.

Here is a little example that is failing for me:

var fs = require('fs');
var exceljs = require('exceljs');

var stream = fs.createWriteStream('richtTextStream.xlsx');
var wb = new exceljs.stream.xlsx.WorkbookWriter({'stream': stream, 'useStyles': true});
var ws = wb.addWorksheet('rich');
var row = ws.getRow(2);
var cell = row.getCell(2);

cell.value = {
  richText: [
    {
      font: {color: {argb: '99E391'}},
      text: 'This part '
    },
    {
      font: {color: {argb: 'FF6565'}},
      text: ' and that one.'
    }
  ]
};

row.commit();
ws.commit();
wb.commit();

If I use a non streaming workbook and write the file using wb.xlsx.writeFile() then I can see the correct formatting.

Any idea what is going on? Is there some missing rendering logic in the Streaming I/O?

Thanks!
