Introduction:
The project aims to develop a robust and efficient web application using ASP.NET Core 8 technologies that allows user to import data files, such as XLSX and CSV into a SQL Server database. This application will provide a seamless and user-friendly experience for importing large volumes of data from various file formats (XLSX, CSV) using ASP.NET Core Web API, XML Bulk Insert, Dapper, CsvHelper, EPPlus and coding best practices.

Key Features:
» XLSX and CSV File Support: The application supports importing data from both XLSX and CSV file formats.
» File Validation and Error Handling: Before data import, files are validated for format and structure. Detailed error handling provides informative messages to users.
» Mapping and Transformation: Data mapping and transformation allow users to map columns from files to database fields and perform necessary transformations during import.
» Data Import Performance Optimization: The application optimizes data import performance using XML Bulk Insert and Dapper to efficiently insert large volumes of data into the SQL Server database.

Tools and Technology Used:
» C#
» ASP.NET Core 8 Web API
» ASP.NET Core 8 Razor Pages
» Clean Architecture
» Dapper as ORM
» XML Bulk Insert
» CsvHelper
» EPPlus
» Bootstrap
