 # Open Excel Files in Syncfusion React Spreadsheet
 
-The Syncfusion React Spreadsheet allows you to open Excel files (.xlsx) by reading the file, converting it into the client‑side Spreadsheet model, and rendering it with full support for data, styles, formats, and more.
+The React Spreadsheet component follows an open, server‑assisted workflow to import Excel files accurately and efficiently. When a user uploads an Excel file, the component sends it to the server instead of handling the parsing in the browser. This ensures smooth performance even for large or heavily formatted workbooks.
+
+On the server, the [`Syncfusion.EJ2.Spreadsheet library`](https://www.nuget.org/packages/Syncfusion.EJ2.Spreadsheet.AspNet.Core), built on top of [`Syncfusion XlsIO`](https://help.syncfusion.com/document-processing/excel/excel-library/net/overview), reads the Excel file and extracts all relevant details—data, styles, formulas, formatting, and sheet structure. The server then converts this information into a Spreadsheet‑compatible JSON workbook.
+
+Once the processing is complete, the JSON data is returned to the client, where the React Spreadsheet component renders the workbook in the browser. This process preserves the original Excel layout and ensures the imported content appears with full fidelity.
 
 To enable opening Excel files, set the [`allowOpen`](https://ej2.syncfusion.com/react/documentation/api/spreadsheet/index-default#allowopen) property to **true** and specify the service url using th [`openUrl`](https://ej2.syncfusion.com/react/documentation/api/spreadsheet/index-default#openurl) property. The control will send the uploaded file to this endpoint, where it is processed and returned as JSON for the Spreadsheet to render.

 # Save Excel Files in Syncfusion React Spreadsheet
 
-The Syncfusion React Spreadsheet allows you to save spreadsheet data as Excel files by sending the client‑side Spreadsheet model to the server, where it is processed and exported with full support for data, styles, formats, and more.
+When exporting an Excel file from the React Spreadsheet component, the workflow is handled through a clear server‑side process. First, the Spreadsheet content displayed in the browser is serialized into a structured JSON workbook. This JSON contains all the necessary details—such as data, formatting, formulas, styles, and sheet structure.
+
+This JSON workbook is then sent to the server, where the [`Syncfusion.EJ2.Spreadsheet library`](https://www.nuget.org/packages/Syncfusion.EJ2.Spreadsheet.AspNet.Core) uses [`Syncfusion XlsIO`](https://help.syncfusion.com/document-processing/excel/excel-library/net/overview) to convert the JSON data into a fully formatted Excel file. XlsIO rebuilds the workbook with complete fidelity, preserving all the features applied in the Spreadsheet.
+
+Since, the server is responsible for generating the final Excel file, the total export time can vary depending on the workbook’s complexity, including the number of sheets, amount of formatting, and usage of advanced features like formulas or conditional formatting. Once the generation is complete, the Excel file is returned to the client for download.
 
 To enable saving Excel files, set the [`allowSave`](https://ej2.syncfusion.com/react/documentation/api/spreadsheet/index-default#allowsave) property to **true** and specify the service URL using the [`saveUrl`](https://ej2.syncfusion.com/react/documentation/api/spreadsheet/index-default#saveurl) property. When a save action is triggered, the control sends the spreadsheet model to this endpoint, where it is processed and returned as a downloadable Excel file.
