Examples

1. Converting API JSON to YAML

Backend Developer
Background
A developer received a large JSON response from a REST API and needs to include it in a YAML-based documentation file.
Problem
Manually rewriting JSON to YAML is error-prone and time-consuming.
How to Use
Paste the JSON into the input, select 'JSON to YAML', and set the indent size to 2.
Example Config
Direction: JSON to YAML, Indent: 2
Outcome
The tool outputs a clean, correctly indented YAML block ready for documentation.

2. Preparing Config for Deployment

DevOps Engineer
Background
An engineer needs to convert a YAML configuration file into JSON to satisfy a legacy system's input requirements.
Problem
The legacy system strictly requires JSON format, but the team prefers managing configurations in YAML.
How to Use
Paste the YAML content, select 'YAML to JSON', and set the indent size to 4 for better readability.
Example Config
Direction: YAML to JSON, Indent: 4
Outcome
The YAML file is converted into a valid JSON object with 4-space indentation, ready for deployment.
