EasyXLS

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

Concept

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

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

EasyXLS allows loading an XLSX document. Once the XLSX 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 XLSX format or other format (XLS, XLSB, XML Spreadsheet, XML, TXT, CSV or HTML).
It can be used to load an already formatted XLSX file as a template, add data and save back the file in XLSX format. In this way, a lot of written code that formats the XLSX file can be avoided.

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

Concept in action

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

Import data from XLSX file having one sheet

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

Import data from XLSX file having multiple sheets

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

I. Usually the first sheet is the active sheet inside an XLSX file. If this is your case or if you are importing data from another active sheet use ExcelDocument.easy_ReadXLSXActiveSheet_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_ReadXLSXSheet_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 by reading the XLSX file using ExcelDocument.easy_LoadXLSXFile method.
Then, import the sheet data using ExcelDocument.easy_ReadExcelWorksheet_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 XLSX 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 XLSX file to DataSet or ResultSet have parameters that permit importing only ranges of cells.

Import all XLSX file structures

EasyXLS allows you to import the whole XLSX 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.

The first above code sample shows how to achieve this goal.

The generated XML document structure is described in the EasyXLS.xsd schema file. The Excel data can be converted to XLSX file with one single line of code using ExcelDocument.easy_ReadXLSXSheet_AsXML method or ExcelDocument.easy_ReadXLSXActiveSheet_AsXML method.
