How to use JSON Redactor

  1. Paste your JSON, then enter one field name or pointer rule per line.
  2. Choose a replacement value or remove matching fields.
  3. Inspect the result and match count before sharing the exported file.

What to expect

A bare field name matches that exact name at any depth. A pointer such as /users/*/email matches one wildcard segment. Matching is case-sensitive. Removing array entries replaces them with null to preserve indexes. This is a rule-based tool, not a guarantee that every secret has been found.

JSON Redactor FAQ

How do I redact all email fields?

Enter email on its own line. To target only a specific part of the document, use a pointer such as /user/email.

What if a key contains a slash?

In a JSON Pointer, encode / as ~1 and ~ as ~0. A bare field-name rule can also match a literal key.
