Customer Data Hasher
Convert email / phone / name lists to SHA-256 — ready for Google Customer Match, Meta CAPI, or offline conversion uploads. Runs entirely in your browser.
Header optional. Columns: email, phone, first_name, last_name.
How normalization works
- Email: lowercased, trimmed.
- Phone: stripped to digits + leading +; double-zero international prefix becomes +.
- Name: lowercased, trimmed, accents stripped (Google + Meta convention).
- All hashes are computed locally — your data never leaves the browser.
