Cleanor Labs
These sections explain the job in plain language and set expectations for what the tool should do well.
To scan JSON for PII, paste your JSON into the tool. It walks every key and value, including nested objects and arrays, and uses pattern heuristics to flag values that look like personal or sensitive data, listing each one by its JSON path so you can find it quickly.
The scan runs entirely in your browser, so the JSON you are checking never leaves your device — which matters when the whole point is privacy. After reviewing the findings, you can export a redacted version where flagged values are masked, ready to paste safely into a ticket, doc, or chat.
This scanner uses practical heuristics to spot common sensitive patterns: email addresses, phone numbers, IP addresses, URLs, API tokens, and secret-like strings. It is designed to catch the values people most often forget to remove before sharing a payload.
Because it is heuristic and intentionally lite, it is a fast cleanup aid rather than a compliance-grade classifier. It may flag harmless values that match a pattern, or miss unusual formats, so treat the findings as a helpful checklist to review by hand, not a legal guarantee.
Short answers for the questions people usually have before trying a utility like this.
Yes. This JSON PII scanner is completely free to use with no signup or account required.
No. The scan runs entirely in your browser on your own device, so the JSON you check is never uploaded to a server and stays private.
Yes. Nested objects and arrays are walked, and every finding is reported with its JSON path so you can locate it.
No. It is a heuristic scanner for practical cleanup and review before sharing JSON. It is not a compliance-grade classifier.
Yes. You can export a redacted JSON output with flagged values masked, ready to share more safely.
Every tool on Cleanor is free with no sign-up, no credits, and no limits. Files are processed privately in your browser. Looking for on-device phone cleanup and Premium features? That lives in the Cleanor app.
Paste JSON, inspect likely PII by path, and export both findings JSON and an optional redacted JSON output locally.
