Join documents together using C++

C++ Cloud SDK to combine several documents and export the result to almost any office format

Use C++ library to merge Word, PDF, Web documents via REST API. Easily combine two or more documents into a single file using C++.

Combine Word, PDF, Web documents using C++ REST API

Easily merge documents together in various formats in C++ code. This C++ library is designed to combine Word, PDF, Web documents into a single file using the REST API, i.e. by passing HTTPS calls over the Internet.

This is a professional Cloud-native document-merging solution that provides C++ programmers with both great development flexibility and powerful features. Joining files together is often used when it is necessary to create a set of documents of the same structure, each of which contains unique data. By merging documents, you can automate your digital workflows and offload some routine parts of the process to fast and efficient document-processing C++ software.

Merge multiple files into one in C++

You may need to combine documents together in many cases. For example, you may want to combine multiple files together before printing or archiving.

Merging documents together can be part of a whole integrated technology for creating documents from disparate data sources. Such tasks involve the use of a full-featured file format manipulation C++ library that will process sets of files and merge them together in the shortest possible time, creating a compact and accurate output.

To merge documents in C++, you need at least two source files. For a quick start, check out the C++ code example below.

C++ code example to merge documents using REST API
Input files
Upload files you want to combine
Upload files you want to combine
Output format
Select the target format from the list
using namespace aspose::words::cloud;

auto config = std::make_shared<ApiConfiguration>(L"####-####-####-####-####", 
   L"##################");
auto wordsApi = std::make_shared<WordsApi>(config);

auto document = std::shared_ptr<std::istream>(new std::ifstream(
   std::filesystem::path(L"Input1.docx"), std::istream::binary));

auto mergeDocument = std::make_shared<aspose::words::cloud::models::DocumentEntry>();
// Load a document to append from the Cloud storage.
mergeDocument->setHref(std::make_shared<std::wstring>(
   L"Input2.docx"));
mergeDocument->setImportFormatMode(
   std::make_shared<std::wstring>(L"KeepSourceFormatting"));

auto documentEntries = 
   std::make_shared<std::vector<std::shared_ptr<aspose::words::cloud::models::DocumentEntry>>>();
documentEntries->push_back(mergeDocument);

auto documentList = 
   std::make_shared<aspose::words::cloud::models::DocumentEntryList>();
documentList->setDocumentEntries(documentEntries);
std::shared_ptr<requests::AppendDocumentOnlineRequest> appendDocumentOnline(
    new requests::AppendDocumentOnlineRequest(
        document, documentList
    )
);
wordsApi->appendDocumentOnline(appendDocumentOnline);

How to use C++ to merge PDF, Word, Web documents and many other file formats

  1. Install C++ Cloud SDK and add the reference (import the library) to your C++ project.
  2. Open the source file in C++ using REST API.
  3. Load a document to append from the Cloud storage.
  4. Call the 'AppendDocumentOnline()' method, passing the output filename with the required extension.
  5. Get the the combined result as a single file.
