FlexGrid allows for both synchronous and asynchronous data importing and exporting. To let your users continue to work on the web page while FlexGrid prepares the document and your browser downloads it, use FlexGrid's asynchronous export method.
Format and Style
If you need to style cell content, FlexGrid components retain style while importing and exporting data. This allows users to retain all of the styles and layout properties assigned, whether in FlexGrid or Excel.
