ToolsSoup's CSV to YAML converter is a free online tool that turns CSV — from a spreadsheet or export — into clean YAML. The first row becomes the keys, every other row becomes a list item, and quoted fields and commas are handled correctly. Everything runs in your browser — no uploads, no sign-up, and nothing ever leaves your device.

      

        
What is a CSV to YAML converter?

        
A CSV to YAML converter reads comma-separated values and rewrites them as YAML, a human-friendly format used widely for configuration. The header row becomes the keys and each data row becomes one item in a YAML list of mappings. It is a quick way to turn a spreadsheet of settings, seed data, or fixtures into YAML you can drop into a config file or a CI pipeline.

Converting CSV with ToolsSoup takes just a few seconds:

How are quotes and special values handled?

        
Fields wrapped in double quotes can contain commas, line breaks, and escaped quotes. When a value could be misread as YAML — a number stored as text, a value with a colon, or a keyword like true or null — the converter wraps it in quotes so the output stays valid. Turn off type parsing to keep every value as a string.

How is the CSV mapped to YAML?

          
The first row is the header and becomes the keys. Each following row becomes one mapping in a YAML list, with the header names as keys and the row's cells as values.

        

        

          
Does it handle commas inside values?

          
Yes. Any field wrapped in double quotes can contain commas, line breaks, and escaped quotes, exactly as the CSV standard specifies.

        

        

          
Why are some values quoted in the YAML?

          
Values are quoted only when leaving them bare would change their meaning — numbers stored as text, values containing a colon, or YAML keywords like true and null. Everything else stays unquoted for readability.

        

        

          
Is my data safe?

          
Absolutely. All conversion happens locally in your browser using JavaScript, so your CSV is never sent to or stored on any server.
