Developer CSV to JSON Converter using Node.js API.

CSV (Comma-Separated Values) is a lightweight and widely used format for storing tabular data in plain text. However, JSON (JavaScript Object Notation) is a more structured and hierarchical data format that is ideal for APIs, web applications, and data interchange between systems. Converting CSV to JSON helps developers modernize workflows, enhance integration capabilities, and streamline data processing.

In this article, you’ll learn how to convert CSV files to JSON using Node.js API, a powerful REST API that simplifies document format transformations in the cloud.

const convertApi = new ConvertApi(config);
const fileApi = new FileApi(config);

Step 2: Now upload the input CSV file to the Cloud storage:

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

Step 3: Set conversion options for (CSV → JSON):

const settings = new ConvertSettings();
settings.filePath = "input.csv";
settings.format = "json";
settings.outputPath = "converted/ConversionFile.json";
let request = new groupdocs.ConvertDocumentRequest(settings);

Step 4: Execute the Conversion process:

convertApi.convertDocument(request)
  .then(response => {
    console.log("CSV successfully converted to JSON:", response);
  })
  .catch(err => {
    console.error("Conversion failed:", err);
  });

CSV to JSON Conversion via cURL

If you prefer using terminal or integrating into DevOps pipelines, the cURL approach works perfectly.

Step 1: Generate JWT Access Token:

curl -v "https://api.groupdocs.cloud/connect/token" \
-X POST \
-d "grant_type=client_credentials&client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET" \
-H "Content-Type: application/x-www-form-urlencoded" \
-H "Accept: application/json"

Step 2: Trigger Conversion API:

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 "{  
    \"FilePath\": \"{inputFile}\",
    \"Format\": \"json\",
    \"LoadOptions\": {    \"Format\": \"csv\"  },
    \"OutputPath\": \"{resultantFile}\"
    }"

Replace <JWT_TOKEN> with the token from Step 1.
