Convert PDF to Excel in C#

PDF documents containing tabular data, financial reports, or structured information often need to be converted to Excel format for further analysis, calculations, or data manipulation. While PDFs preserve formatting and ensure consistent presentation, they don’t provide the interactive capabilities that Excel offers for data processing.

Converting PDF to Excel transforms static tabular content into dynamic spreadsheets where users can sort, filter, perform calculations, and create charts. This conversion is particularly valuable for financial data, statistical reports, and any structured information that benefits from Excel’s analytical capabilities.

For organizations that receive reports, invoices, or data sheets in PDF format, the ability to convert these documents to Excel becomes essential for data analysis workflows. It eliminates the need for manual data entry and reduces the risk of transcription errors while enabling sophisticated data processing.

Streamlining Workflows with our .NET SDK

What makes this feature even more valuable is how effortlessly it can be implemented using our SDK. With just a few lines of code, developers can integrate PDF to Excel conversion directly into their applications. Whether you’re building a data processing pipeline or adding conversion functionality to a business application, our SDK delivers accurate conversion capabilities right out of the box.

Preparing the project

The first step is to initialize the SDK by registering the license. This needs to be done only once during the application’s lifetime and must occur before executing any further logic (see Getting Started with .NET SDK(opens in a new tab) for more details.)

using GdPicture14;

LicenseManager licence = new LicenseManager();
licence.RegisterKEY("");

Proceeding with the conversion

With the SDK successfully initialized, you can begin working with the classes it offers. In this guide, we’ll concentrate on the GdPictureDocumentConverter class. You can initialize GdPictureDocumentConverter using a using statement, which ensures proper lifecycle management of the converter instance.

using GdPictureDocumentConverter converter = new GdPictureDocumentConverter();

After initializing the converter instance, you can use it to load a PDF file. The SDK supports multiple integration methods, allowing flexibility in how you connect with your application. The source file can be specified either via a file path or a stream. In this guide, we’ll focus on using a file path as the source.

This path can be either absolute or relative. Here, we’ll load the file from the application’s working directory, which typically resides next to the executable unless otherwise configured.

converter.LoadFromFile(@"input_table.pdf");

Once the PDF file is loaded into memory, you can perform various operations on it. For a complete list of available functionalities, refer to the API reference(opens in a new tab).

Our goal is to export this document to Excel format. The converter intelligently analyzes the PDF structure, identifies tabular data, and reconstructs it as a properly formatted Excel spreadsheet. Just like when opening the PDF file, the saving functionality offers flexibility in output methods.

converter.SaveAsXLSX(@"output.xlsx");

Error handling

The .NET SDK handles errors by providing return codes. Both methods presented in this guide are returning a GdPictureStatus enum value. This helps troubleshooting and doing error handling logic. See Handling Errors with .NET SDK Guide for more information.

Conclusion

That’s all it takes to convert a PDF document containing tabular data into an Excel file! The conversion process intelligently preserves data structure while making it fully editable and analyzable in Excel. You can also download this ready-to-use sample package, fully configured to help you dive into the .NET SDK and explore seamless PDF to Excel conversion capabilities.
