YAML to JSON Converter

World's Simplest JSON Tool

Free online YAML to JSON converter. Just load your YAML in the input field and it will automatically get converted to JSON. In the tool options, you can prettify the output JSON by adding indentation – spaces or tabs. Additionally, you can minify the output JSON by setting the number of indentation spaces to zero. Created for developers by developers from team Browserling.

JSON Indentation

Use spaces to prettify the output JSON file.
Set the number of spaces per indent level. (If the number of spaces is 0, then the JSON will be minified.)
Use tabs to prettify the output JSON file.

What Is a YAML to JSON Converter?

This tool converts YAML (YAML Ain't Markup Language) files into JSON (JavaScript Object Notation) data structures. YAML is known for its convenient and readable data representation as it uses indentation and key-value pairs to depict hierarchial data. JSON, on the other hand, is a stricter format, employing curly braces, square brackets, and colons to separate objects, arrays, and elements. While humans often prefer YAML for its readability and ease of editing, machines and robots prefer JSON for its simplicity and strictness. Often, there's no choice but to use JSON as it's the required data format. For example, there are APIs, systems, and databases that only accept JSON input. When converting YAML to JSON, you can also customize the output JSON format by adjusting the options of this tool. Specifically, you can enhance the readability of the output data by indenting the JSON with spaces or tabs. Alternatively, you can create a compact JSON file with the smallest possible size by using 0 spaces for indentation. If you ever need to convert JSON back to YAML, you can use our Convert JSON to YAML program. Json-abulous!

YAML to JSON Converter Examples

Convert YAML to JSON Array

In this example, we convert a YAML list of Earth elements ("fire", "water", "earth", "air") into a minimized JSON array without indentation. The tool encloses the data in square brackets to create a JSON array and wraps each element in double quotes, maintaining the original order of YAML elements.

- fire - water - earth - air
["fire","water","earth","air"]
Required options
These options will be used automatically if you select this example.
Use spaces to prettify the output JSON file.
Set the number of spaces per indent level. (If the number of spaces is 0, then the JSON will be minified.)

Transform YAML with Nested Lists into JSON

In this example, we transform YAML with key-value pairs and nested lists into JSON format. The input includes various animals and the sounds they make. Some animals, like "dog", have multiple sounds, forming a nested YAML list which is transformed into a nested JSON array. The tool accurately converts all key-value pairs into equivalent and syntactically valid JSON objects and arrays, which are prettified with two-space indentation.

cow: moo sheep: baa dog: - bark - woof - howl frogs: - croak - ribbit
{ "cow": "moo", "sheep": "baa", "dog": [ "bark", "woof", "howl" ], "frogs": [ "croak", "ribbit" ] }
Required options
These options will be used automatically if you select this example.
Use spaces to prettify the output JSON file.
Set the number of spaces per indent level. (If the number of spaces is 0, then the JSON will be minified.)

Turn YAML Profile Data to JSON

In the input of this example, we load personal profile data in YAML format and turn it into a JSON file. The YAML structure contains information about a person, including their name, surname, status, city, age, and interests. The resulting JSON file preserves the hierarchical structure of the original YAML file, correctly wrapping data in curly and square brackets and adding tab indentation for better readability.

person: first_name: Jenna last_name: Mullins status: active city: Copenhagen age: 25 interests: - music - reading - traveling
{ "person": { "first_name": "Jenna", "last_name": "Mullins" }, "status": "active", "city": "Copenhagen", "age": 25, "interests": [ "music", "reading", "traveling" ] }
Required options
These options will be used automatically if you select this example.
Use tabs to prettify the output JSON file.
