Here is an example of creating a file upload component:

@using DataJuggler.Blazor.FileUpload

<FileUpload CustomSuccessMessage="Your file uploaded successfully." 
    OnReset="OnReset" ResetButtonClassName="localbutton" ShowStatus="false"
    PartialGuidLength="12" MaxFileSize=@UploadLimit FilterByExtension="true" 
    ShowCustomButton="true"  ButtonText="Upload Excel" OnChange="OnFileUploaded"
    CustomButtonClassName="@OrangeButton" AllowedExtensions=".xlsx"
    ShowResetButton="false" AppendPartialGuid="true"
    CustomExtensionMessage="Only .xlsx extensions are allowed." 
    InputFileClassName="customfileupload" Visible=false Status="Refresh"
    FileTooLargeMessage=@FileTooLargeMessage>
</FileUpload>

To handle the File Upload event 'OnFileUploaded'. The code shown also starts a progress bar timer and reads the sheet names using Nuget package DataJuggler.Excelerate (the Nuget package that powers Blazor Excelerate).

#region OnFileUploaded(UploadedFileInfo file)
/// <summary>
/// This method On File Uploaded
/// </summary>
public void OnFileUploaded(UploadedFileInfo file)
{
    // if the file was uploaded
    if (!file.Aborted)
    {
        // Show the Progressbar
        ShowProgress = true;
        
        // if the ProgressBar
        if (HasProgressBar)
        {
            // Start the Timer
            ProgressBar.Start();
        }
        
        // Create a model
        GetSheetNamesModel model = new GetSheetNamesModel();
        
        // Set the model
        model.FullPath = file.FullPath;
        
        // Store this for later
        ExcelPath = file.FullPath;
        
        // reload the model
        HandleDiscoverSheets(model);
    }
    else
    {
        // for debugging only
        if (file.HasException)
        {
            // for debugging only
            string message = file.Exception.Message;
        }
    }
}
