### Open an excel file from blob data
119+
120+
By default, the Spreadsheet control provides an option to browse files from the local file system and open them within the control. If you want to open an Excel file from blob data, you need to fetch the blob data from the server or another source and convert this blob data into a `File` object. Then, you can use the `open` method in the Spreadsheet control to load that `File` object.
121+
122+
Please find the code to fetch the blob data and load it into the Spreadsheet control below.

### Open an Excel file located on a server
148+
149+
By default, the Spreadsheet control provides an option to browse files from the local file system and open them within the control. If you want to load an Excel file located on a server, you need to configure the server endpoint to fetch the Excel file from the server location, process it using `Syncfusion.EJ2.Spreadsheet.AspNet.Core`, and send it back to the client side as `JSON data`. On the client side, you should use the `openFromJson` method to load that `JSON data` into the Spreadsheet control.
150+
151+
```csharp
152+
public IActionResult Open([FromBody] FileOptions options)
153+
{
154+
OpenRequest open = new OpenRequest();

string filePath = _env.ContentRootPath.ToString() + "\\Files\\" + options.FileName + ".xlsx";
156+
// Getting the file stream from the file path.
157+
FileStream fileStream = new FileStream(filePath, FileMode.Open);
158+
// Converting "MemoryStream" to "IFormFile".
159+
IFormFile formFile = new FormFile(fileStream, 0, fileStream.Length, "", options.FileName + ".xlsx");
160+
open.File = formFile;
161+
// Processing the Excel file and return the workbook JSON.
162+
var result = Workbook.Open(open);
163+
fileStream.Close();
164+
return Content(result);

### Save an excel file as blob data
527+
528+
By default, the Spreadsheet control saves the Excel file and downloads it to the local file system. If you want to save an Excel file as blob data, you need to set `needBlobData` property to **true** and `isFullPost` property to **false** in the `beforeSave` event of the spreadsheet. Subsequently, you will receive the spreadsheet data as a blob in the `saveComplete` event. You can then post the blob data to the server endpoint for saving.
