YAML to JSON

Use this tool when YAML-managed configuration needs to move into a JSON-based workflow. It is especially helpful for CI files, service definitions, and deployment settings that would be tedious to rewrite by hand.

Conversion happens only in the browser, so internal configuration can be inspected without uploading it to a server.

When to use it

• When you want to turn YAML settings into JSON request bodies for testing
• When you need a JSON view of Helm, CI, or app configuration files
• When the YAML looks valid but you want to inspect the resulting structure more directly

What to check before converting

YAML is sensitive to indentation and implicit type parsing, so it helps to review the structure before converting.

• indent: useful when you want readable JSON for docs or review
• sortKeys: useful for stable ordering and cleaner diffs
• escapeUnicode: useful when you want non-ASCII characters rendered in escaped form

Common mistakes

• Mixing tabs and spaces in YAML indentation
• Letting YAML interpret intended strings as numbers or booleans
• Misaligning indentation between arrays and objects
• Expecting every advanced YAML feature to flatten into simple JSON cleanly

Example input

name: zzzbbb
active: true
items:
  - 3
  - 1

Example output

{
  "name": "zzzbbb",
  "active": true,
  "items": [3, 1]
}
