Use Cases

• Converting configs for Kubernetes or CI

  Turn a JSON configuration object into YAML for a Kubernetes manifest, GitHub Actions workflow, or Docker Compose file.

• Making API payloads easier to read

  Convert a JSON API response into YAML when reviewing or documenting it, since YAML is often easier to scan than nested braces.

• Drafting readable settings files

  Turn generated JSON settings into YAML for tools and frameworks that expect configuration in YAML format.

• Preparing infrastructure-as-code snippets

  Convert a JSON data structure into YAML before pasting it into an infrastructure-as-code template or values file.

Examples

{ "meta": { "free": true, "version": 2 } }

meta:
  free: true
  version: 2

[{ "slug": "json-formatter", "category": "developer" }]

- slug: json-formatter
  category: developer

Benefits

• ✓Turn JSON configs and payloads into readable YAML
• ✓Prepare Kubernetes, CI, or Docker Compose snippets quickly
• ✓No account, upload, or install required

Best Practices

• Validate or format your JSON first if you are unsure it is well-formed.
• Review quoting on values that look like numbers or booleans.
• Use the download button to save reusable .yaml snippets.

Common Mistakes

• Pasting JSON with trailing commas or comments, which are not valid JSON.
• Expecting anchors, tags, or comments in the output.
• Assuming string values that look numeric will stay unquoted.

All processing is client-side in your browser. Your JSON is never uploaded to ToolMint servers.
