FAQ
What field types are available?
22 built-in types: Chinese name, mobile number, checksum-valid ID number, address, email, UUID, IPv4, timestamp, color and more — combine them freely.
How many records can I generate?
Up to 10,000 per run, exported as JSON or CSV with download or copy.
Is the data real?
No — everything is randomly composed from built-in dictionaries. ID numbers pass checksum math but point to fictional people. For testing only.
