Concept
EasyXLS™
library allows you to export a list to an Excel file. The data in cells can be formatted using predefined formats or user-defined formats.
EasyXLS can be successfully used inclusively to export large Excel files having big volume of data with fast exporting time.
Concept in action
The below example shows how to export list to Excel in .NET, Java and export lists of data extracted from database in PHP, ASP, C++, VB6, VBS and Coldfusion.

The screen shot below provides an example of an exported Excel file from a list.
Formatting cells
EasyXLS™ enables you to format cells, rows and columns in order to set the fonts and colors.
|
Export List to XLSX, XLSB, XLSM and XLS files
This code sample shows how to export a list to an XLS file. Similarly, you can export a List to XLSX file using ExcelDocument.easy_WriteXLSXFile_FromList method or export a List to XLSB file using ExcelDocument.easy_WriteXLSBFile_FromList method.
|
Export List to Excel file with multiple sheets
For an Excel file having multiple sheets, the List can be inserted using ExcelWorksheet.easy_insertList method and the Excel file must be exported using ExcelDocument.easy_WriteXLSFile method.
