CSV to YAML Converter
Paste CSV, get structured YAML — header row as keys, auto type detection — copy or download as .yml
You have data in a CSV file — exported from a spreadsheet, database, or analytics tool — and need it in YAML format for a configuration file, a static site generator, or a CI/CD pipeline definition.
What This Tool Does
Paste CSV and get structured YAML output instantly. The converter uses the header row as keys and maps each data row to a YAML mapping. Numeric values are preserved as numbers, not strings. Download the result as a .yml file.
Everything runs in your browser. Your data never leaves your device.
When to Use This
- Static site data — convert CSV data files to YAML for Jekyll, Hugo, or Eleventy data files
- Configuration generation — create YAML configs from spreadsheet data
- Test fixtures — generate YAML test data from CSV test cases
- DevOps workflows — transform CSV inventories into YAML-based Ansible inventories
FAQ
Does this send my data to a server?
No. All conversion happens entirely in your browser.
How are data types handled?
Numbers, booleans, and null values are automatically detected and output as native YAML types rather than quoted strings.
