C++ API to Convert CSV to PDF and PDF to CSV Format
To achieve these conversions, you will need Aspose.Cells for C++ and Aspose.PDF for C++ APIs. The former is a C++ library for creating, reading, and modifying Excel files, whereas the latter is an API for working with PDF files. We will use Aspose.Cells for C++ API to convert CSV files to PDF format and Aspose.PDF for C++ API to convert PDF files to CSV format. You can either install the APIs through NuGet or download them directly from the Downloads section.
PM> Install-Package Aspose.Cells.Cpp
PM> Install-Package Aspose.PDF.CppConvert CSV Files to PDF Format
The following are the steps to convert CSV files to PDF format.
- Create an instance of the ILoadOptions class.
- Load the CSV file by creating an object of the IWorkbook class using the ILoadOptions instance created earlier.
- Save the file in PDF format using the IWorkbook->Save (intrusive_ptr<Aspose::Cells::Systems::String> fileName, Aspose::Cells::SaveFormat saveFormat) method.
The following is the sample code to convert CSV files to PDF format using C++.
Converting a PDF File to CSV Format
The following are the steps to convert a PDF file to CSV format.
- Load the PDF file using the Document class.
- Create an instance of the ExcelSaveOptions class.
- Set the format to CSV using ExcelSaveOptions->set_Format (ExcelSaveOptions::ExcelFormat value) method.
- Save the CSV file using the Document->Save (System::String outputFileName, System::SharedPtr<SaveOptions> options) method.
The following is the sample code to convert a PDF file to CSV format using C++.
Convert Selected PDF Pages to a CSV File
Aspose.PDF for C++ also provides you the ability to include specific PDF pages in the converted CSV file. To achieve this, you can follow the following steps.
- Load the PDF file using the Document class.
- Create an instance of the ExcelSaveOptions class.
- Set the format to CSV using ExcelSaveOptions->set_Format (ExcelSaveOptions::ExcelFormat value) method.
- Create a new object of the Document class to represent the CSV file.
- Loop through the pages of the PDF file using the Document->get_Pages() method.
- Within the loop, specify the condition for selecting the desired pages.
- Add the pages to the newly created Document object using the Document->get_Pages()->Add (System::SharedPtr<Page> const & entity) method.
- Save the CSV file using the Document->Save (System::String outputFileName, System::SharedPtr<SaveOptions> options) method outside the loop.
The following is the sample code to include selected PDF pages in the CSV file.
Converting PDF Pages to Individual CSV Files
With Aspose.PDF for C++, you can also convert PDF pages to individual CSV files. To achieve this, you can follow the following steps.
- Load the PDF file using the Document class.
- Create an instance of the ExcelSaveOptions class.
- Set the format to CSV using ExcelSaveOptions->set_Format (ExcelSaveOptions::ExcelFormat value) method.
- Loop through the pages of the PDF file using the Document->get_Pages() method.
- Within the loop, create a new object of the Document class to represent the CSV file.
- Add the pages to the newly created Document object using the Document->get_Pages()->Add (System::SharedPtr<Page> const & entity) method.
- Save the CSV file using the Document->Save (System::String outputFileName, System::SharedPtr<SaveOptions> options) method.
The following is the sample code to convert PDF pages to individual CSV files using C++.
