json to html

Perform JSON to HTML conversion online with Node.js.

Displaying JSON (JavaScript Object Notation) data in HTML format is essential when building dashboards, visual reports, or embedding structured data into web content. Rather than manually formatting data, you can now convert JSON to HTML in Node.js using the powerful GroupDocs.Conversion Cloud SDK — a REST API that simplifies document transformation.

In this tutorial, we’ll walk you through how to convert a JSON file to a clean, browser-ready HTML document using Node.js.

📌 Quick Navigation

🚀 Why Convert JSON to HTML?

HTML is the standard format for displaying data on the web. By converting JSON (JavaScript Object Notation) to HTML, developers can:

  • ✅ Render structured data in user-friendly layouts.
  • ✅ Embed JSON in websites or web apps.
  • ✅ Create readable tables or blocks from nested JSON.
  • ✅ Export API responses into readable HTML pages.

⚙️ Install GroupDocs Node.js SDK

GroupDocs.Conversion Cloud SDK for Node.js offers a lightweight way to integrate file format conversion into your JavaScript-based applications. To get started:

  1. Install via npm:
npm install groupdocs-conversion-cloud --save
  1. Get your API credentials (Client ID and Client Secret) from the GroupDocs Cloud Dashboard. For more information, you may follow the instructions specified in this tutorial.

🛠️ Convert JSON to HTML in Node.js

Here’s how to convert a JSON file into HTML using GroupDocs.Conversion Cloud SDK in 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 JSON file to Cloud

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

📌 Step 3: Set conversion options (JSON → HTML)

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

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

💻 Convert JSON to HTML via cURL

While using GroupDocs.Conversion Cloud with cURL commands, you can also perform JSON to HTML conversion. This approach not only simplifies automation and integration into various workflows, but it provides platform-independent, easy to script, and allows for seamless, high-quality data transformation without requiring extensive coding.

Generate a JWT access token based on client credentials and then execute the following command:

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

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

  • You may consider executing the following command if the requirement is to save the resultant HTML to local drive:
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\"}"

✅ Conclusion

Converting JSON to HTML using GroupDocs.Conversion Cloud SDK for Node.js helps developers generate dynamic, readable, and presentable web content from structured data. Whether you’re building admin dashboards, automating reports, or working with JSON API responses, this SDK simplifies the process with clean HTML output.
