EasyXLS

Import XLS file in .NET, Java and other programming languages

EasyXLS™ library allows you to import data from an XLS file or other sheet elements like cell formatting, charts, pivot tables, comments, images and others.

EasyXLS can be successfully used to also import large XLS files having big volume of data with fast importing time.

EasyXLS allows loading an XLS document. Once the XLS is loaded in memory, the user can process data, add more features to the file (like formulas, cell formatting, comments, hyperlinks, images, data validations, page setup, charts, etc), and save the file back in XLS binary format or other format (XLSX, XLSM, XLSB, XML Spreadsheet, XML, TXT, CSV or HTML).
It can be used to load an already formatted XLS file as a template, add data and save back the file in XLS binary format. In this way, a lot of written code that formats the XLS file can be avoided.

EasyXLS permits you to import Excel files without Excel installed, without Interop, without OLEDB or any other additional software installed.

Import entire XLS file

The below source code sample is a common code about how to import an XLS file. The source code shows how to load and import an XLS file that is used as a base template, add more data to the XLS file and save the new workbook.
After that, the best techniques about importing data from XLS file like importing Excel data to DataTable, GridView, DataGridView, DataSet, ResultSet, DataGrid and List are shown.

Import data from XLS file having one sheet

Importing data from an XLS file, if the XLS file has only one sheet, is the easiest approach. The Excel data can be imported with one single line of code using ExcelDocument.easy_ReadXLSActiveSheet_AsDataSet method.
The above code sample shows how to achieve this goal.

Import data from XLS file having multiple sheets

There are three approaches for importing data from an XLS file with multiple sheets.

I. Usually the first sheet is the active sheet inside an XLS file. If this is your case or if you are importing data from another active sheet use ExcelDocument.easy_ReadXLSActiveSheet_AsDataSet method.

II. For importing data from an Excel sheet and the name of the sheet is known, EasyXLS recommends the use of ExcelDocument.easy_ReadXLSSheet_AsDataSet method.

III. For importing data from an Excel sheet and the name of the sheet is not known, the first step is to find the sheet name by using ExcelDocument.easy_ReadXLSFile_SheetNames method.
Then, import the sheet data using ExcelDocument.easy_ReadXLSSheet_AsDataSet method.

Import data from range of Excel cells

EasyXLS enables you to import Excel data either from the entire sheet or from ranges of cells. Importing only a range of cells is a very useful option especially for large XLS 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 XLS file to DataSet or ResultSet have parameters that permit importing only ranges of cells.

EasyXLS allows you to import the whole XLS 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.
