常见问题
Quick answers.
›What data types can I generate?
The generator supports standard field types including names, addresses, UUIDs, timestamps, and placeholder text. You can also define custom ranges for numeric values and boolean flags.
›Is there a limit on the number of records?
Browser memory is the only practical limit. While you can typically generate several thousand records for local testing, extremely large files may slow down the browser tab.
›Can I use my own JSON structure?
Yes. You can define a custom schema with specific keys and assign data types to each field to match your existing API architecture.
›is my data schema sent to a server?
No. The logic for constructing the mock JSON runs strictly client-side on your device. Neither your schema nor the generated records are transmitted over the network.
