How to use this tool
Choose between one and two hundred rows and select the format. Fields are fixed, so compare their names and types with the target schema before importing the output.
Results and examples
Three JSON rows form an array of records containing id, name and email. SQL output assumes a users table and therefore needs review rather than direct execution against a production database.
Limitations
- Identifiers are UUID-like values, not a guarantee of collision freedom or formal UUID conformance.
- Email-shaped samples should not be treated as real people to contact.
