Convert HTML to JSON using Node.js

This section explains the details on how we can quickly and easily convert an HTML to JSON format using Node.js:

Step 1: Import SDK and configure API:

const { Configuration, ConvertApi, FileApi, UploadFileRequest, ConvertSettings, ConvertDocumentRequest } = require("groupdocs-conversion-cloud");
const config = new Configuration("YOUR_CLIENT_ID", "YOUR_CLIENT_SECRET");
const convertApi = new ConvertApi(config);
const fileApi = new FileApi(config);

Step 2: Upload the HTML file to the Cloud storage:

const fs = require("fs");
const uploadRequest = new UploadFileRequest("source.json", fs.createReadStream("source.html"));
await fileApi.uploadFile(uploadRequest);

Step 3: Set conversion options (HTML → JSON)

const settings = new ConvertSettings();
settings.filePath = "input.html";
settings.format = "json";
settings.outputPath = "converted/resultant.json";

const request = new ConvertDocumentRequest(settings);
await convertApi.convertDocument(request);
console.log("The HTML to JSON conversion completed successfully.");

HTML to JSON via cURL Command

Using the cURL command-line tool to convert HTML to JSON is an excellent choice for users who prefer a lightweight, code-free, or automated integration. It’s ideal for server-side scripting, continuous integration workflows, or systems that require programmatic API calls without writing a full SDK-based implementation.

Benefits of Using cURL for Conversion:

  • Script-friendly: Easily integrate into shell scripts or cron jobs.
  • No SDK required: Directly access the REST API.
  • Ideal for DevOps: Seamless integration into CI/CD pipelines.
  • Flexible: Works on any system with cURL installed.

Now, generate your personalized Java Web Access Token and execute the following command to perform HTML to JSON conversion.

curl -v "https://api.groupdocs.cloud/v2.0/conversion" \
-X POST \
-H "accept: application/json" \
-H "authorization: Bearer {JWT_TOKEN}" \
-H "Content-Type: application/json" \
-d "{  \"StorageName\": \"internal\",  \"FilePath\": \"{inputFile}\",  \"Format\": \"html\",  \"resultantPath\": \"{myResultant}\"}"

Please replace inputFile with the name of input JSON file, resultantPath with the name of resultant HTML file and JWT_TOKEN with a personalized JWT access token.

  • If your requirement is to save the resultant JSON to local drive, please try using the following cURL command:
curl -v "https://api.groupdocs.cloud/v2.0/conversion" \
-X POST \
-H "accept: application/json" \
-H "authorization: Bearer {accessToken}" \
-H "Content-Type: application/json" \
-d "{  \"StorageName\": \"internal\",  \"FilePath\": \"input.json\",  \"Format\": \"html\"}"
