Privacy Policy

Last updated: July 2, 2026

Your Data Stays in Your Browser — Guaranteed

JSON to CSV Converter is a client-side only tool. All JSON data you upload or paste is processed entirely in your browser. No data is ever sent to any server, stored, logged, or shared with third parties.

Zero data collection. Zero server uploads. 100% local processing.

To be absolutely clear: your data is only processed locally in your browser and is never uploaded to any server. When you upload a JSON file or paste content, the data is read into your browser's memory using the FileReader API, converted to CSV format by JavaScript running in your browser, and then offered as a download — all without a single network request carrying your data. Once you close the browser tab or refresh the page, all processed data is completely gone.

What We Don't Collect

  • We do not collect, store, or transmit your JSON input or CSV output.
  • We do not require registration or personal information to use this tool.
  • We do not use cookies to track your activity or personal data.
  • We do not share any information with third-party services.

What We May Collect

  • Anonymous usage analytics — We may use privacy-respecting analytics (e.g., page views) to improve the tool. No personal data or file contents are included.
  • Browser local storage — Your browser may cache preferences (e.g., theme settings) locally on your device. This data never leaves your machine.

File Security

When you upload a JSON file or paste content:

  • The file is read directly into your browser's memory using the FileReader API.
  • Conversion happens locally via JavaScript — no network requests are made with your data.
  • Downloaded CSV files are generated and saved entirely on your device.
  • Once you close the tab or clear the page, all processed data is gone.

Third-Party Services

This tool does not integrate with any third-party services that collect personal data. There are no advertising networks, social media trackers, or external analytics platforms embedded in this site.

Children's Privacy
