Examples

Simple YAML Object

name: John
age: 30
city: NYC
{"name":"John","age":30,"city":"NYC"}

💡 YAML key-value pairs to JSON object

Nested Structures

user:
  name: John
  email: [email protected]
{"user":{"name":"John","email":"[email protected]"}}

💡 YAML indentation becomes JSON nesting

Arrays

colors:
  - red
  - blue
  - green
{"colors":["red","blue","green"]}

💡 YAML lists to JSON arrays

Common Mistakes to Avoid

⚠️

Incorrect YAML indentation

Solution: YAML is whitespace-sensitive. Mixed spaces/tabs or wrong indentation breaks parsing. Use 2 or 4 spaces consistently.

⚠️

Not quoting special values

Solution: YAML interprets yes/no/on/off as booleans, numbers as integers. Quote them if you want strings: "yes" not yes.

⚠️

Losing YAML-specific features

Solution: YAML anchors (&ref, *ref) and tags don't translate to JSON. Converted output expands these into full values.
