Is the generated data truly random?

Names and addresses are drawn from built-in lists using a cryptographically seeded random number generator, making them unpredictable but not truly random in the information-theoretic sense. The data is suitable for testing but not for cryptographic purposes.

Can I use this data in production?

No — the generated data is fictional and should only be used for testing, development, and demonstration purposes. Never use fabricated personal data in production systems.

Frequently Asked Questions

What does random-data do?

random-data generate random test data in json, csv, xml, yaml, tsv, and sql. Results appear immediately — no page reloads, no waiting for a server response.

What input does random-data accept?

Paste text directly into the input field, or type your data. Most operations handle Unicode, special characters, and multi-line inputs without issue.

How large an input can I process?

There is no hard limit imposed by this tool. Very large inputs (multi-MB text) process within your browser's available memory. For files larger than 50 MB, a command-line tool may be faster.

Can I download the output?

Yes — every output panel includes a Copy to Clipboard button and a Download as file option. Outputs are saved as plain text or the appropriate file format for the operation.
