Convert a CSV File to XML in C/C++
While the CSV format is great for organizing large sets of data without any formatting or program specifications, it does not translate well for web-based purpose. If you need to change it to a viewer-friendly, machine-readable file format, XML is the best option. The following API will allow you to convert CSV files to XML in C/C++ instantly, without the tedious and complex process of manual conversion.
Our first step is to install libcurl in the C/C++ project:
libcurl/7.75.0
With the installation complete, we can move on to calling the conversion function like so:
CURL *curl;
CURLcode res;
curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_CUSTOMREQUEST, "POST");
curl_easy_setopt(curl, CURLOPT_URL, "https://api.cloudmersive.com/convert/csv/to/xml");
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, "columnNamesFromFirstRow: <boolean>");
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);
curl_mime_free(mime);
}
curl_easy_cleanup(curl);]]
Done! Your new XML file will be returned in no time. To retrieve your API key to plug into the code, simply visit the Cloudmersive website to register for a free account.
