What this demonstrates
Mail merge on the server
The server captures a workbook template with fixed bindings and a repeating row band, saves it as TXWB, reloads a clean copy, merges validated business data, inspects diagnostics, and exports a workbook or PDF.
APIs used
Workbook.SetMailMergeAsync()
Workbook.MergeAsync()
ServerSheetControl.LoadAsync()
SaveAsync()

Default invoice total: 540. Diagnostics include merge warnings and formula errors.
Independent server processing
The controller validates the inputs, creates a request-owned ServerSheetControl, awaits each operation, and returns generated bytes. The browser displays the workbook or PDF returned by .NET. The generation endpoint works without a browser editor.
The Code panel shows this sample's actual implementation and the shared hosting code. Downloads contain the current document; changes are not stored on the server.
