How to import Excel data to SQL table in C# and VB.NET

Concept

EasyXLS™ library allows you to import Excel data to SQL tables. The data can be imported from an Excel sheet or from the active Excel sheet. The entire sheet data or only data from ranges of cells can be imported.

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

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

The source code samples can be integrated in:
- ASP.NET web pages
- Windows applications
- Windows Forms (WinForms)
- Console applications
- Windows service applications
- ASP.NET MVC web applications

Concept in action

The below example shows how to import Excel file to SQL database in C# or VB.NET. The Excel will be imported to a DataSet and later, the records can be inserted into the database using SQL syntax.

Source code sample

C#.NET
VB.NET

Import Excel to SQL Server, MySQL or any other database

Once the Excel data is imported to DataSet, the records can be processed and entered into database using INSERT, UPDATE or other SQL commands specific to SQL Server, MySQL, Oracle, MS Access or any other database.

Import Excel file having one sheet to SQL table

Importing the Excel file data to SQL database, if the Excel 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 for XLS file
- ExcelDocument.easy_ReadXLSXActiveSheet_AsDataSet method for XLSX file
- ExcelDocument.easy_ReadXLSBActiveSheet_AsDataSet method for XLSB file

The above code sample shows how to achieve this goal.

Import Excel file having multiple sheets to SQL table

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

I. Usually the first sheet is the active sheet inside an Excel file. If this is your case or if you are importing data from another active sheet use:
- ExcelDocument.easy_ReadXLSActiveSheet_AsDataSet method for XLS file
- ExcelDocument.easy_ReadXLSXActiveSheet_AsDataSet method for XLSX file
- ExcelDocument.easy_ReadXLSBActiveSheet_AsDataSet method for XLSB file

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 for XLS file
- ExcelDocument.easy_ReadXLSXSheet_AsDataSet method for XLSX file
- ExcelDocument.easy_ReadXLSBSheet_AsDataSet method for XLSB file

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 Excel file using:
- ExcelDocument.easy_LoadXLSFile method for XLS file
- ExcelDocument.easy_LoadXLSXFile method for XLSX file
- ExcelDocument.easy_LoadXLSBFile method for XLSB file

Then, import the sheet data in DataSet using ExcelDocument.easy_ReadExcelWorksheet_AsDataSet method.

Import range of Excel cells to SQL table

EasyXLS enables you to import Excel data to SQL database 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.

Import XLSX, XLSB, XLSM and XLS files to SQL table

This code sample shows how to import XLS file to SQL database. In a similar way, you can import XLSX, XLSM, XLSB files to database using:
- ExcelDocument.easy_ReadXLSXActiveSheet_AsDataSet or ExcelDocument.easy_ReadXLSXSheet_AsDataSet method for XLSX and XLSM files
- ExcelDocument.easy_ReadXLSBActiveSheet_AsDataSet or ExcelDocument.easy_ReadXLSBSheet_AsDataSet method for XLSB files
