Quick use cases
Create flat YAML fixtures for application tests. Test YAML parsing and data-import workflows. Prepare readable sample records for development and documentation.
Common generator issues
A consumer expects nested configuration instead of a flat record list. Scalar values are interpreted as an unexpected type. Field names do not match the target schema.
Generator feature notes
- Each generated record is an item in a YAML list.
- Configured fields appear as flat key-value pairs.
- The output is intended for record-based data, not nested application or Kubernetes configuration.
Feature boundaries
Generate up to 5,000 records per file. Use up to 25 fields and 10 files per run. The generator produces a YAML list of flat records.

What YAML structure does the generator produce?
It produces a YAML list in which each item is a flat record containing the configured fields.
Can it generate Kubernetes manifests?
No. The generator creates flat record datasets and does not produce the nested schema required by Kubernetes manifests.
Can I control YAML field names and value types?
Yes. Configure the name and data type of each field before generating the dataset.
