+# Connecting Web Services for Spreadsheet Open and Save in ASP.NET Core
+
+This guide explains how to set up and connect local web services for open and save operations in the Syncfusion Spreadsheet component using ASP.NET Core.
+
+## Overview
+
+By default, the Syncfusion Spreadsheet component uses Syncfusion-hosted endpoints for file operations:
+
+```ts
+openUrl: 'https://document.syncfusion.com/web-services/spreadsheet-editor/api/spreadsheet/open',
+saveUrl: 'https://document.syncfusion.com/web-services/spreadsheet-editor/api/spreadsheet/save'
+```
+
+These demo services are intended solely for demonstration purposes and are not recommended for production or development environments.
+
+## How-To Guide: Create a Local ASP.NET Core Web API
+
+### Create a New ASP.NET Core Web API Project
+
+Follow the official Microsoft tutorial to create a controller-based Web API project:
+
+[Tutorial: Create a controller-based web API with ASP.NET Core | Microsoft Learn](https://learn.microsoft.com/en-us/aspnet/core/tutorials/first-web-api?view=aspnetcore-10.0&source=recommendations&tabs=visual-studio#create-a-web-api-project)
+
+### Install Required Dependencies
+
+For spreadsheet open and save operations, install the following NuGet packages:
+
+| Platform | Assembly | NuGet Package |
+|---------------|------------------------------------------|---------------|
+| ASP.NET Core | Syncfusion.EJ2.AspNet.Core
Syncfusion.XlsIORenderer.Net.Core | [Syncfusion.EJ2.AspNet.Core](https://www.nuget.org/packages/Syncfusion.EJ2.AspNet.Core)
[Syncfusion.XlsIORenderer.Net.Core](https://www.nuget.org/packages/Syncfusion.XlsIORenderer.Net.Core) |
+
+For more details, see the [dependencies section on nuget.org](https://www.nuget.org/packages/Syncfusion.EJ2.Spreadsheet.AspNet.Core#dependencies-body-tab).
+
+### Add Open and Save Controllers
+
+Add the following controller actions to enable open and save functionality:
+
+```csharp
+// Open action
+[HttpPost]
+[Route("Open")]
+public IActionResult Open([FromForm] IFormCollection openRequest)
+{
+ OpenRequest open = new OpenRequest();
+ if (openRequest.Files && openRequest.Files.Count > 0) {
+ open.File = openRequest.Files[0];
+ return Content(Workbook.Open(open));
+ }
+ return BadRequest("No file uploaded.");
+}
+
+// Save action
+[HttpPost]
+[Route("Save")]
+public IActionResult Save([FromForm] SaveSettings saveSettings)
+{
+ if(saveSettings && saveSettings.JSONData) {
+ return Workbook.Save(saveSettings);
+ }
+}
+```
+
+### Configure File Size Limits
+
+To support large Excel files, configure file size limits in your server settings.
+
+**web.config**
+```xml
+
+
+
+
+
+
+
+
+
+
+
+```
+
+**Program.cs**
+```csharp
+builder.Services.Configure(options =>
+{
+ options.MultipartBodyLengthLimit = int.MaxValue;
+ options.ValueLengthLimit = int.MaxValue;
+});
+
+builder.WebHost.ConfigureKestrel(options =>
+{
+ options.Limits.MaxRequestBodySize = int.MaxValue;
+});
+```
+
+### Enable CORS (Cross-Origin Resource Sharing)
+
+Edit `Program.cs` to allow cross-origin requests:
+
+```csharp
+var MyAllowSpecificOrigins = "AllowAllOrigins";
+builder.Services.AddCors(options =>
+{
+ options.AddPolicy(MyAllowSpecificOrigins, builder =>
+ {
+ builder.AllowAnyOrigin()
+ .AllowAnyMethod()
+ .AllowAnyHeader();
+ });
+});
+
+var app = builder.Build();
+app.UseCors(MyAllowSpecificOrigins);
+```
+
+### Run the Web API Project
+
+Build and run your Web API project. For detailed instructions, refer to:
+
+[Run the ASP.NET Core Web API project](https://learn.microsoft.com/en-us/aspnet/core/tutorials/first-web-api?view=aspnetcore-10.0&source=recommendations&tabs=visual-studio#run-the-project)
+
+---
+
+### Configuring the Client-Side URLs
+
+Once your local service is launched, configure the openUrl and saveUrl properties in client application to use the local endpoints.
+
+```js
+
+```
+
+For more information, refer to the following [blog post](https://www.syncfusion.com/blogs/post/host-spreadsheet-open-and-save-services).

+# Connecting Web Services for Spreadsheet Open and Save in ASP.NET MVC
+
+This guide explains how to set up and connect local web services for open and save operations in the Syncfusion Spreadsheet component using **ASP.NET MVC**.
+
+## Overview
+
+By default, the Syncfusion Spreadsheet component uses Syncfusion-hosted endpoints for file operations:
+
+```ts
+openUrl: 'https://document.syncfusion.com/web-services/spreadsheet-editor/api/spreadsheet/open',
+saveUrl: 'https://document.syncfusion.com/web-services/spreadsheet-editor/api/spreadsheet/save'
+```
+
+These demo services are intended solely for demonstration purposes and are not recommended for production or development environments.
+
+## How-To Guide: Create a Local ASP.NET MVC Web Service
+
+### Create a New ASP.NET MVC Project
+
+Follow the official Microsoft tutorial to create an ASP.NET MVC 5 project:
+
+[Getting Started with ASP.NET MVC 5 | Microsoft Learn](https://learn.microsoft.com/en-us/aspnet/mvc/overview/getting-started/introduction/getting-started)
+
+### Install Required Dependencies
+
+For spreadsheet open and save operations, install the following NuGet packages:
+
+| Platform | Assembly | NuGet Package |
+|---------------|------------------------------------------|---------------|
+| ASP.NET MVC5 | Syncfusion.XlsIO.AspNet.Mvc5
Syncfusion.ExcelToPdfConverter.AspNet.Mvc5
Syncfusion.Pdf.AspNet.Mvc5
Syncfusion.ExcelChartToImageConverter.AspNet.Mvc5
Syncfusion.EJ2.MVC5 | [Syncfusion.XlsIO.AspNet.Mvc5](https://www.nuget.org/packages/Syncfusion.XlsIO.AspNet.Mvc5)
[Syncfusion.ExcelToPdfConverter.AspNet.Mvc5](https://www.nuget.org/packages/Syncfusion.ExcelToPdfConverter.AspNet.Mvc5)
[Syncfusion.Pdf.AspNet.Mvc5](https://www.nuget.org/packages/Syncfusion.Pdf.AspNet.Mvc5/)
[Syncfusion.ExcelChartToImageConverter.AspNet.Mvc5](https://www.nuget.org/packages/Syncfusion.ExcelChartToImageConverter.AspNet.Mvc5)
[Syncfusion.EJ2.MVC5](https://www.nuget.org/packages/Syncfusion.EJ2.MVC5) |
+
+### Add Open and Save Actions in Controller
+
+Add the following action methods to your controller (e.g., `SpreadsheetController`) to enable open and save functionality:
+
+```csharp
+using System.Web;
+using System.Web.Mvc;
+using Syncfusion.EJ2.Spreadsheet;
+
+public class SpreadsheetController : Controller
+{
+ // Open action
+ [HttpPost]
+ public ActionResult Open(OpenRequest openRequest)
+ {
+ if (openRequest != null && openRequest.File != null)
+ {
+ var result = Workbook.Open(openRequest);
+ return Content(result);
+ }
+ return new HttpStatusCodeResult(400, "No file uploaded.");
+ }
+
+ // Save action
+ [HttpPost]
+ public void Save(SaveSettings saveSettings)
+ {
+ if(saveSettings && saveSettings.JSONData) {
+ Workbook.Save(saveSettings);
+ }
+ }
+}
+```
+
+### Configure File Size Limits
+
+To support large Excel files, configure file size limits in your server settings.
+
+**web.config**
+```xml
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+```
+
+### Enable CORS (Cross-Origin Resource Sharing)
+
+Cross-Origin Resource Sharing (CORS) allows your ASP.NET MVC application to accept requests from other domains (such as when your client app and server are running on different ports or hosts).
+
+**How to Enable CORS in ASP.NET MVC**
+
+1. Open `Global.asax.cs` in your project.
+2. Add the following code to the `Application_BeginRequest` method:
+
+```csharp
+protected void Application_BeginRequest()
+{
+ // Allow all origins. For production, specify allowed origins instead of '*'.
+ HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");
+ HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods", "GET, POST, OPTIONS");
+ HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers", "Content-Type, Accept");
+
+ // Handle preflight requests
+ if (HttpContext.Current.Request.HttpMethod == "OPTIONS")
+ {
+ HttpContext.Current.Response.End();
+ }
+}
+```
+
+### Run the MVC Project
+
+After adding the controller codes and above mentioned configurations, build and run the MVC project (F5 or Ctrl+F5 in Visual Studio).
+
+---
+
+### Configuring the Client-Side URLs
+
+Once your local service is launched, configure the openUrl and saveUrl properties in client application to use the local endpoints.
+
+```js
+
+```
+
+For more information, refer to the following [blog post](https://www.syncfusion.com/blogs/post/host-spreadsheet-open-and-save-services).
