Here Mudassar Ahmed Khan has explained with an example, how to export DataGridView data to Excel file with formatting i.e. Colors and Styles in Windows Forms (WinForms) Applications using C# and VB.Net.
DataGridView cannot be exported directly to Excel file and hence need to generate a DataTable and export the DataTable to Excel file.
The DataTable will be exported to a formatted Excel file using ClosedXml library which is a wrapper of OpenXml.
