Mask JSON data

Mask Sensitive Data in JSON

Hide private values before you share JSON. Partly mask fields like names and emails, fully mask passwords and card numbers, and let auto-detect find emails, phones, cards and tokens for you.

How to use it

1. Paste JSON.
2. List keys to mask partly or fully, or leave auto-detect on.
3. Copy the masked JSON and share it.

What it does

• Partial and full masking
• Auto-detects emails, phones, cards, tokens and passwords
• Keeps the JSON structure

Questions

Is the original data sent anywhere?

No. Masking runs in your browser, so the real values never leave your device.
