JSON to YAML Converter

World's Simplest JSON Tool

Free online JSON to YAML converter. Just load your JSON in the input field and it will automatically get converted to YAML. You can also type-as-you-go and see how various JSON structures look like in YAML. It can't get any easier than this! Created for developers by developers from team Browserling.

What Is a JSON to YAML Converter?

This tool converts JSON (JavaScript Object Notation) data structures into YAML (YAML Ain't Markup Language) configuration files. JSON and YAML are two popular data serialization and configuration formats commonly used in various applications, especially in web development and server configuration files. JSON primarily consists of arrays and objects expressed as key-value pairs, and it uses curly braces ({}), square brackets ([]), and colons (:) to create data structures. YAML, on the other hand, is a more human-friendly data serialization language and doesn't use that many braces or brackets. It uses indentation and a hyphen (-) to represent nested structures, making it visually easy to read. Often, converting JSON to YAML simplifies the maintenance of data, especially for system administrators. If you need to convert YAML back to JSON, you can use our Convert YAML to JSON tool. Fun fact: every valid JSON in itself is valid YAML (but not the other way around). Json-abulous!


JSON to YAML Converter Examples

Click to try!

Convert a JSON Object to YAML

In this example, we convert a JSON object containing a list of perfect numbers into the YAML format. Upon conversion, the program removes unnecessary curly braces and square brackets for YAML and generates an indented hierarchical YAML structure. The output YAML retains the same data but is much more readable and maintainable due to its simple format (no more curly braces or array brackets!)

{ "numbers": "perfect", "list": [ 6, 28, 496 ] }
numbers: perfect list: - 6 - 28 - 496

Turn a JSON Array into a YAML List

In this example, we're migrating our chat application from JSON config files to YAML config files. We convert a JSON array containing different emotions that users can select into a YAML list. The input JSON is compressed without indentation, spaces, or line breaks. When it gets converted into YAML, the program rewrites it into a multi-line list format that is easier to view and edit.

["happy","sad","angry","calm","joyful"]
- happy - sad - angry - calm - joyful

JSON with Nested Objects

In this example, we load a more complex JSON file with nested objects and arrays. This file contains information about a fruit, including its name, color, seasonality, and vitamins. The program parses the JSON, finds all key-value pairs, objects, and arrays, and outputs matching YAML with correct indentation for nested objects, and hyphen-prefixed lines for the elements of the "seasons" array.

{ "fruit": "strawberry", "color": "red", "seasons": [ "spring", "summer" ], "vitamins": { "vitamin c": "high", "vitamin k": "moderate" } }
fruit: strawberry color: red seasons: - spring - summer vitamins: vitamin c: high vitamin k: moderate
