About the Random YAML Generator
The Random YAML Generator creates YAML documents filled with randomly generated data, making it useful for testing, development, and simulation purposes without hand-writing sample YAML from scratch.
Choose how many top-level entries (rows) and key-value pairs per entry (columns) you need, and the tool instantly builds a properly indented YAML document with a random alphanumeric value for each field — ready to feed into a parser, config loader, or test fixture.
