ExcelConverter

ExcelConverter is the BaseConverter subclass selected by ConverterFactory for .xls/.xlsx source files. It delegates the byte transformation to the Syncfusion ExcelToPdfConverter engine and declares its SourceConversionType; timing, status assembly, and error capture come from BaseConverter.

Purpose

• Convert an Excel workbook stream to PDF via Syncfusion.ExcelToPdfConverter (BR-SFC-003).
• Identify itself to ConverterFactory and downstream consumers as the OfficeExcelDoc conversion type.

Context

• Namespace: PdfAPI.SyncFusionCore
• Assembly/package: PdfAPI.SyncFusionCore (Pdf.Local.Client NuGet package)

Public members

Member	Signature	Purpose
ExcelConverter	ExcelConverter()	Creates a ready-to-use ExcelConverter instance for ConverterFactory to invoke against Excel source documents (.xls/.xlsx); the constructor body is empty*, so no state is established beyond the base type's fields.
ConversionType	override SourceConversionType ConversionType { get; }	Returns SourceConversionType.OfficeExcelDoc, identifying this converter's source format to ConverterFactory and to the assembled PdfResult.

Inherited public members

Members in this section are inherited from BaseConverter in PdfAPI.SyncFusionCore. They are available on this type through inheritance.

Member	Signature	Purpose	Origin
Convert	PdfResult Convert(Stream stream, ConvertRequest request)	Executes the full conversion: times the operation, invokes ConfigureConverter and ConvertItem, and assembles a PdfResult with Status, Elapsed, and PdfProcessorType = Syncfusion; captures rather than propagates conversion exceptions (BR-SFC-006, BR-SFC-010).	PdfAPI.SyncFusionCore — BaseConverter

Behavioral notes

• Conversion is delegated entirely to the Syncfusion ExcelToPdfConverter engine; this type does not reimplement workbook parsing.
• A conversion failure is captured by the inherited Convert method and reported through the result rather than thrown (BR-SFC-010).

Constraints and usage notes

• Not intended to be constructed directly by application code; ConverterFactory constructs and invokes it based on the source file extension.
