YAML Output
Why use a private CSV to YAML converter?
Converting CSV to YAML for config files or Kubernetes data is a common task. This converter handles it entirely in your browser using PapaParse and js-yaml — no data is uploaded or transmitted.
How it works
PapaParse parses the CSV (auto-detecting the delimiter), maps each row to an object using the header row as keys, then js-yaml serializes the resulting array to YAML block style. Each CSV row becomes a YAML mapping entry.
Common use cases
- Converting spreadsheet data to YAML for use in Ansible playbooks or Helm values
- Transforming CSV config data to YAML for GitHub Actions or Docker Compose
- Converting lookup tables from CSV to YAML for application config files
Frequently asked questions
- Is my data safe to convert here?
- Yes. All conversion happens in your browser. No data is transmitted to any server.
- What input format is expected?
- A CSV with a header row is expected. Each row becomes a YAML mapping where the header values are the keys.
