defaultCellStyle API about workbook

That's part of the protobi/js-xlsx fork, not the main branch. Styles in general aren't exported with the main branch yet.

The API is the same as for the .s attribute. On testing just now, it seems that Excel is only paying attention to the font.name and font.sz attributes, not fill color.

XLSX.writeFile(workbook, OUTFILE, {defaultCellStyle: { font: { name: "Courier New", sz: 18}}});

For other cells, you might define a constant style and reference that for other cells:

This worked for me:

defaultCellStyle: {
  font: {name: 'Arial', sz: '12'},
  fill: {
    fgColor: { rgb: 'FFFFFFFF' }
  }
}

Are there docs on what styles are available for the s attribute?

Not yet. That's important to add. For now can use the example.js as a reference.

@protobi good enough, for now.

I don't see anything about borders, are those supported yet?

Sorry! Borders aren't in yet. Shouldn't be too difficult to add now there's a framework for it. May get to that this coming week, is that sufficient for your timeline?

That's more then fine! If you need any help let me know.
