Replace sensitive PII values in JSON with realistic fake data for GDPR compliance, safe sharing, and QA. Configurable key-to-strategy mapping. No upload.

Replace PII fields like email, name, phone, and SSN with realistic fake data so you can share JSON safely with QA, vendors, or open-source repos. Choose hash, mask, fake, or remove strategies and customise which keys to scrub.
Free is enough for most one-off jobs. Pro raises the file and batch caps; Pro + Media unlocks GB-scale streaming and unlimited duration.
Larger files supported on Developer (5 GB CSV) and Enterprise (unlimited). All processing happens in your browser — files never reach a server.
Drop a JSON file
Drag a .json onto the dropzone or paste text.
Configure PII keys and strategy
Default keys are email/name/phone/address/ssn. Pick `fake` to replace with realistic values, `hash` for deterministic redaction, `mask` for fixed asterisks, or `remove` to drop the field entirely.

Field count and modified-fields are reported. Verify a sample before sharing externally.
The tool helps but is not a certification. It replaces values matching common PII keys; combine it with manual review and your own policy review for compliance.
Yes — hash strategy produces the same output for the same input within a single run, so you can preserve referential integrity (same email always maps to same hash).
Add it to the PII keys list. Matching is case-insensitive — `customer_email` and `customerEmail` are both detected.

Remove specific keys from every level of a JSON object or array. Bulk-strip PII fields like id, password, and email recursively. No upload required.
Remove null, undefined, empty strings, and empty arrays from JSON recursively. Clean up API responses and data exports. Browser-based, no upload.
Automatically fix common broken JSON: missing quotes on keys, trailing commas, single quotes, and unescaped characters. Browser-based, no upload.
