Choose your file format. Everything runs locally in your browser.
Redact CSV
Detect and redact PII in comma-separated files. Names, emails, TFNs, phone numbers — found and masked instantly.
Redact XLSX
Scan Excel spreadsheets across all sheets. Multi-sheet support with per-sheet detection and redaction.
Redact PDF
Open, preview, and permanently redact sensitive content in PDF documents. Pixel-level precision.
Redact JSON
Scan nested JSON structures for PII. Traverse objects and arrays recursively — detect sensitive values at any depth.
Redact XML
Parse XML documents including FHIR and HL7 healthcare formats. Namespace-aware detection with element-level redaction.
Morph PII
Replace real PII with realistic fake values. Same input always produces the same output. Scan first, then toggle Morph.
Generate Fake Data
Create realistic fake datasets from templates — KYC, medical, HR, CRM, loan. Australian formats with valid structure.
Why WorkLens
Three things no other redaction tool can claim — and you can verify each one.
Zero Network Requests
Open DevTools. Drop a file. Watch the Network tab — zero outbound requests. Your data never touches a server. Prove it yourself.
Mathematically Verified
ID numbers like TFN, Medicare, ABN, and credit cards are validated using official mathematical checks — not guessed. Works globally with deep Australian support. More regions coming.
Audit Receipt
Every scan produces a signed fingerprint that proves what was scanned and what was found. If anything is altered, the signature won't match.
Prove It Yourself
No other redaction tool can pass this test.
