Convert a Word File to HTML in C/C++

The DOCX format is widely recognized as the most reliable and easy-to-use format for creating text documents. On the other hand, HTML is one of the best formats to work with for web-based documents. Due to their different uses and the complexity of the DOCX file’s internal design, it can be quite the undertaking to manually convert a DOCX file to HTML. However, you can instantly convert any DOCX file to HTML by running the following API in C/C++, automatically simplifying the conversion process.

To begin, you will need to install libcurl in your C/C++ project:


Then, you can call the function with the following code:

CURL *curl;
CURLcode res;
curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_CUSTOMREQUEST, "POST");
curl_easy_setopt(curl, CURLOPT_URL, "");
curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);
curl_easy_setopt(curl, CURLOPT_DEFAULT_PROTOCOL, "https");
struct curl_slist *headers = NULL;
headers = curl_slist_append(headers, "Content-Type: multipart/form-data");
headers = curl_slist_append(headers, "Apikey: YOUR-API-KEY-HERE");
curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);
curl_mime *mime;
curl_mimepart *part;
mime = curl_mime_init(curl);
part = curl_mime_addpart(mime);
curl_mime_name(part, "inputFile");
curl_mime_filedata(part, "/path/to/file");
curl_easy_setopt(curl, CURLOPT_MIMEPOST, mime);
res = curl_easy_perform(curl);

And just like that, you’re done!
