About this converter

YAML is easier to read and edit than CSV for configuration and structured data. If you have a CSV export from a spreadsheet and need to use that data in a YAML-based config (Ansible playbooks, Kubernetes ConfigMaps, static site data files), this converter does the job. Each row becomes a YAML object with keys from the header row. The conversion runs in your browser. Your data is not uploaded.
