Frequently Asked Questions
- Is the generated YAML valid?
- Yes. Every file parses cleanly with standard YAML parsers, and stays valid even at an exact byte target — the padding is written as YAML comments, which parsers ignore.
- What structure does the YAML have?
- Files contain a sequence of records. Depending on the content type you pick, that is either people and company data, server log entries, or lorem ipsum text.
- Can I use these to test config loading?
- Yes. They are well suited to testing config file size limits, parser performance, and upload endpoints that accept YAML.
