Why this tool exists

Work with the structure, not the noise.

Debug payloads can contain authentication headers, API keys, session identifiers and personal information. This tool walks the complete JSON tree and masks values whose keys or content match common sensitive patterns. Redaction happens locally and produces a separate copy.

01

Mask common password, token, secret and authorization keys

02

Optionally detect email and IP address values

03

Report every redacted JSON path

04

Preserve the original input for side-by-side review

How to use it

From payload to useful result.

  1. Paste the payload locally

    The document is processed only in this browser tab.

  2. Select detection rules

    Key-based secret detection is always applied; email and IP detection are optional.

  3. Review every path

    Automated detection is intentionally conservative. Check the result before posting it publicly.

Common questions

Before you use the output.

Does this guarantee all private data is removed?

No. Sensitive data may use unexpected keys or formats. Always perform a human review before sharing.

Is the original object modified?

No. The tool constructs a redacted copy and leaves the text in the input pane unchanged.
