Remove PII from JSON · 100% client-side

Remove PII from JSON — keep the shape.

Paste a JSON payload — API response, fixture, support ticket. FixAIPrompt parses it, walks the tree, and replaces sensitive values with safe placeholders. The shape, keys, and harmless values stay exactly the same, so the AI you share it with still understands the structure.

Before — risky

{
  "user": {
    "id": "u_4821",
    "email": "priya.iyer@acme.co",
    "phone": "+91 98765 43210",
    "ssn": "501-29-4471",
    "card_number": "4111 1111 1111 1111"
  },
  "auth": {
    "token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1aWQiOiJ1NDgyMSJ9.X9R3pqTuVwXyZ012aBcDeFgHiJkLmNoPqRsTuVwXyZ",
    "api_key": "sk-proj-1QRSt2UvWxYz0abcdef123456ghij789klMnoPqr"
  },
  "metadata": {
    "ip": "49.207.181.22",
    "country": "IN"
  }
}

After — safe to paste

{
  "user": {
    "id": "u_4821",
    "email": "[EMAIL_MASKED]",
    "phone": "[PHONE_MASKED]",
    "ssn": "[SSN_MASKED]",
    "card_number": "[CARD_NUMBER_MASKED]"
  },
  "auth": {
    "token": "[TOKEN_MASKED]",
    "api_key": "[API_KEY_MASKED]"
  },
  "metadata": {
    "ip": "[IPV4_MASKED]",
    "country": "IN"
  }
}

What you get

Detects sensitive JSON keys (password, token, secret, api_key, auth, credential, etc.) and masks the entire value.
Detects in-value PII (emails, phone numbers, SSNs, Aadhaar, credit cards with Luhn validation) — even in fields you didn't think were sensitive.
Preserves valid JSON structure so the output is still copy-paste ready for AI.
If the JSON is invalid, falls back to plain text masking on the original.
Runs entirely in your browser. Nothing uploaded.
