1. Import data from Excel file
EasyXLS allows you to import data from an Excel sheet or from the active Excel sheet. The entire sheet data or only data from ranges of cells can be imported.
// Create an instance of the class that imports Excel files
ExcelDocument workbook = new ExcelDocument();
// Import Excel file
DataSet ds = workbook.easy_ReadXLSXActiveSheet_AsDataSet("C:\\Samples\\Excel file.xlsx");
' Create an instance of the class that imports Excel filesDim workbook As New ExcelDocument
' Import Excel fileDim ds As DataSet = workbook.easy_ReadXLSXActiveSheet_AsDataSet("C:\Samples\Excel file.xlsx")
EasyXLS enables you to import Excel data either from the entire sheet or from a range of cells. Importing only a range of cells is a very useful option especially for large Excel files because it reduces the speed of the import process.
In order to import multiple cell ranges at once from Excel sheet, the range parameter must be passed to the method as union of ranges (multiple ranges separated by comma).
All the methods that allow importing Excel to DataSet have parameters that permit importing only ranges of cells.
5. Import all Excel file structures
EasyXLS allows you to import the whole Excel file with sheets, data inside sheets, formulas, cell formatting, comments, hyperlinks, images, data validation, page setup, macros, groups, filters, charts, pivot tables and pivot charts.
