# JSON to YAML Converter: Switch Formats for Kubernetes and CI/CD
JSON is the language of APIs, but YAML dominates configuration files. Kubernetes manifests, Docker Compose files, GitHub Actions workflows, and CI/CD pipelines all use YAML. FreeToolJet's JSON to YAML Converter converts between both formats instantly — no CLI tools needed.
Why Convert Between JSON and YAML?
- Kubernetes: Generate manifests in YAML, but validate them as JSON.
- Docker Compose: The Compose spec supports both formats, but YAML is the standard.
- CI/CD: GitHub Actions, GitLab CI, and CircleCI all use YAML configuration.
- Terraform: Some providers accept JSON or YAML — convert as needed.
How to Use the Converter
- Paste your JSON or YAML in the input area.
- Select the conversion direction: JSON → YAML or YAML → JSON.
- Choose indentation: 2 spaces (most common) or 4 spaces.
- Copy the converted output.
