Need to export data from sql server to excel sheet in window

Question

Kindly someone help me on this by proving code

Leon D · Answer

Export data to Excel is very simple with Spire.XLS library. First add reference to Spire.Xls.dll (Which you can get from https://www.nuget.org/packages/Spire.XLS/), then refer to below code: DataTable dt = dataSet.Tables[0]; //export datatable to excel Workbook workbook = new Workbook(); Worksheet sheet = workbook.Worksheets[0]; sheet.InsertDataTable(dt, true , 1, 1); workbook.SaveToFile( "insertTableToExcel.xls" ,ExcelVersion.Version97to2003);

Leon D · Answer

I found the reason. When creating the workbook, its default version is 2003. Please specify the version when creating the workbook object, like this: //export datatable to excel Workbook workbook = new Workbook(); workbook.Version = ExcelVersion.2013; Worksheet sheet = workbook.Worksheets[0]; sheet.InsertDataTable(dt, true , 1, 1); workbook.SaveToFile( "insertTableToExcel.xlsx" ,ExcelVersion.Version2013);

Thanks Leon and others for helping me on this issue.

Shankar M · Answer

Thanks now it exports all the data . But when I open that excel file getting an error called

Leon D · Answer

Because you specified the result excel file format as .xls, .xls file can only contain 65536 rows. Please change the format to xlsx with the code I sent before. It should work.

Shankar M · Answer

It fetches only 65536 records

Leon D · Answer

Change the result excel file format to xlsx like this and see if it works: workbook.SaveToFile("insertTableToExcel.xlsx", ExcelVersion.Version2013);

You're very welcome, glad to know my code works :)

Leon D · Answer

Hi Shankar M, You already had the code to connect to sql server and read data into datatable, after that you can just use spire.xls and below code to insert that datatable into xls file. Sorry I don't have sql server database, so cannot provide you the full code. Workbook workbook = new Workbook(); Worksheet sheet = workbook.Worksheets[0]; sheet.InsertDataTable(datatable, true, 1, 1); workbook.SaveToFile("insertTableToExcel.xls",ExcelVersion.Version97to2003);
