What is CSV → YAML?
A CSV→YAML converter: the header row becomes keys and each data row becomes a YAML mapping.
How it works
The shared RFC 4180 CSV parser reads the input, then js-yaml serializes the rows as a list of objects with clean indentation.
- Enter your input. Type or paste your input into the field above — the tool responds instantly.
- Review the result. Output updates live as you type. Everything runs entirely in your browser.
- Copy or download. Use the Copy button to grab the result, or Download to save it as a file.
Examples
Spreadsheet to config
Turn a CSV table into a YAML list of maps — headers become keys, ready to use as seed data or configuration.
Common mistakes
Type inference on import
Numeric strings can become numbers in YAML. The converter keeps values as strings unless you opt into inference.
Frequently asked questions
What if columns are inconsistent?
Rows missing a column get an empty value; extra columns are preserved.
Can it handle large files?
Yes — conversion runs locally, so file size is limited only by the browser.
