What Hide JSON Strings can do:

Hide JSON Strings is perfect when you need to anonymize or protect sensitive data within JSON objects. Whether you need to mask email addresses, names, or other identifiers, this tool allows you to easily replace or remove string fields, all while keeping the rest of the JSON structure intact. With live updates and full control over the output format, it’s a powerful tool for data privacy.

Example:

Before:

{
  "name": "Alice",
  "email": "[email protected]",
  "age": 30,
  "city": "London"
}

With options enabled:

  • Replace Strings with Placeholder: On
  • Remove Strings: Off

After:

{
  "name": "[HIDDEN]",
  "email": "[HIDDEN]",
  "age": 30,
  "city": "London"
}

Common Use Cases:

Use Hide JSON Strings when dealing with private or sensitive information such as personal identifiers, emails, or passwords. It’s ideal for anonymizing data before sharing, logging, or processing, ensuring that confidential information remains protected.

Useful Tools & Suggestions:

Before hiding anything, Extract JSON Keys/Values can help you figure out exactly what’s inside. Then, once you’ve hidden the strings, Obfuscate JSON can be used to further scramble things and keep the structure less readable.
