CSV to YAML Converter

Turn a CSV table into a YAML list of records — header cells become the keys.

Conversion runs locally in your browser. Nothing is uploaded, logged, or stored.

How to use

  1. Paste your CSV into the input panel — the first row is treated as the header.
  2. Pick the delimiter if your file uses semicolons or tabs.
  3. Click Convert to get a YAML list where each row is one record.
  4. Copy or download the .yaml result.

How the conversion works

The CSV is parsed with full RFC 4180 support — quoted fields, embedded delimiters, and newlines are handled correctly. Each data row becomes a YAML mapping keyed by the header cells, producing the list-of- records shape that Kubernetes, Helm, and most config systems expect. Values keep their YAML string form, so ambiguous values like yes or 1.0 are quoted when needed.

Frequently Asked Questions

Is my data uploaded anywhere?+
No. Parsing and serialization happen entirely in your browser.
What YAML structure is produced?+
A top-level list of mappings: one mapping per CSV row, with header cells as keys.
Are quoted CSV fields supported?+
Yes, including escaped double quotes and embedded newlines, per RFC 4180.
What if my CSV has no header?+
The first row will be used as keys. Add a header row first for meaningful key names.
