Rules
Paste a table to choose fields.
Same value + same seed → same replacement.
Generation runs locally. Repeated non-empty values map consistently within each selected field for this exact seed and strategy. Missing values, null, and empty text remain unchanged.

How it works
- Choose a replacement for each field: names, emails, phones, addresses, companies, identifiers, dates, numbers, or a fixed value.
- The same value and seed always give the same replacement, so matching values still match. Change the seed for new values.
- Null, empty, and missing values stay as they are.
- A name, email, and address in one row belong to the same fictional person.
- This reduces exposure. It does not guarantee anonymization.
