DOCX to HTML using cURL Commands

One of the key advantages of using GroupDocs.Conversion Cloud with cURL commands is the simplicity and flexibility it offers. You can easily integrate the conversion process into your workflows or scripts with ease, and automate the DOCX to HTML conversion task efficiently.

The first step in this approach is to generate the JWT access token based on client credentials. Once we have generated the JWT token, we need to execute the following cURL command to convert the Word document to HTML format and save the resultant file to cloud storage.

curl -v "" \
-H "accept: application/json" \
-H "authorization: Bearer {accessToken}" \
-H "Content-Type: application/json" \
-d "{  \"StorageName\": \"internal\",  \"FilePath\": \"{inputFile}\",  \"Format\": \"html\",  \"LoadOptions\": {    \"Format\": \"docx\"  },  \"OutputPath\": \"{resultantHTML}\"}"

Please replace inputFile with the name of input CSV file, resultantHTML with the name of resultant HTML file and accessToken with personalized JWT access token.

  • In order to save the resultant HTML to local drive, please try using the following cURL command:
curl -v "" \
-H "accept: application/json" \
-H "authorization: Bearer {accessToken}" \
-H "Content-Type: application/json" \
-d "{  \"StorageName\": \"internal\",  \"FilePath\": \"{inputFile}\",  \"Format\": \"html\",  \"LoadOptions\": {    \"Format\": \"doc\"  }}" \
-o "myResultant.html"
