Free Online Data Converter (JSON, CSV, XML)

Bitlist's Universal Data Converter allows developers and data analysts to instantly transform data between the most popular formats: JSON (JavaScript Object Notation), CSV (Comma-Separated Values), and XML (Extensible Markup Language).

Key Features

  • JSON to CSV: Perfect for exporting NoSQL database dumps (like MongoDB) or API responses into Excel or Google Sheets for business analysis.
  • CSV to JSON: Essential for converting spreadsheet data into a format that can be used by web APIs and modern applications.
  • XML Parsing: Convert legacy XML configurations or RSS feeds into lightweight JSON for easier processing in JavaScript.
  • Bi-Directional: Swap inputs and outputs instantly to reverse any conversion.
  • Privacy First: All conversions happen locally in your browser. Your sensitive data is never uploaded to any server.

How to Convert Data

Simply paste your raw data into the "Input" panel, select your source format (e.g., XML), choose your target format in the "Output" panel (e.g., JSON), and the tool will automatically convert it. You can then copy the result or download it as a file.

Frequently Asked Questions

Can I convert nested JSON to CSV?

Yes. The tool automatically detects nested arrays (like a list of users) and attempts to flatten them into rows. For simple lists of objects, it works perfectly. For highly complex trees, some structure may be simplified.

Is my data secure?

Absolutely. Unlike many other online converters, Bitlist processes your data using JavaScript right on your device. We do not see, store, or transmit your files.

How do I convert XML attributes?

Our intelligent system converts XML attributes (like <item id="1">) into JSON properties prefixed with @ (e.g., "@id": "1"), ensuring no data is lost during conversion.
