Regex Test Data Generator
Given a regex pattern, generate N example strings that match it. Useful for structured IDs, codes, and format-specific mock values.
Regex Test Data Generator
Generate regex-matching strings for fixtures, testing, and validation workflows.
Input (JSON Envelope)
Provide { pattern, count, seed?, format }. format supports json-array and newline outputs.
Output (Generated Samples)
Regex-matching strings in the selected output format.
Example input and output
{"pattern":"^[A-Z]{2}\\d{4}$","count":5,"format":"json-array"}["AB1234","ZK8821","MQ0047","TP2291","ER6650"]
