  1. Why convert YAML to JSON?

    YAML dominates human-edited configuration because it is compact and readable; JSON dominates APIs, browsers, and programmatic tooling because it maps directly onto data structures. Converting YAML to JSON lets you inspect a config in a tree viewer, feed it into JavaScript with JSON.parse(), store it in a JSON-native database, or diff it against another document.

    It also catches mistakes: YAML is famously sensitive to indentation, and a single misaligned space can change meaning. Seeing the equivalent JSON makes the real structure obvious.

  2. How the conversion works

    JsonDrift parses your YAML into an in-memory data structure using a spec-compliant parser, then serializes it as pretty-printed JSON. Mappings become objects, sequences become arrays, and scalars are typed as strings, numbers, booleans, or null. Anchors and aliases are resolved to plain values so the output is portable JSON that any parser accepts.

  3. Supported YAML features

    • Nested mappings and sequences (objects and arrays)
    • Scalars: strings, numbers, booleans, and null
    • Anchors and aliases, resolved to concrete values
    • Multi-document streams (first document by default)
    • Kubernetes, CI/CD, and docker-compose structures

  4. Common use cases

    Developers reach for YAML to JSON conversion whenever a human-friendly config has to be consumed by machine-friendly tooling.

    • Convert Kubernetes YAML manifests to JSON for kubectl or APIs
    • Turn GitHub Actions or GitLab CI workflows into JSON for analysis
    • Load docker-compose or Ansible vars into a JavaScript app
    • Pipe config into the JSON Validator or Schema Validator

FAQ

Frequently asked questions

How do I convert YAML to JSON?

Paste your YAML into the input panel and JsonDrift instantly returns the equivalent JSON, which you can copy or download. Everything runs in your browser.

Are YAML comments preserved?

No. JSON has no comment syntax, so comments are dropped during conversion. The data itself is fully preserved.

Can I convert Kubernetes YAML?

Yes, standard Kubernetes manifests convert cleanly. For multi-document files, convert each document separately, and always re-validate with your cluster tooling.

Is my YAML uploaded to a server?

No. Parsing and conversion happen entirely in your browser, so private configs and secrets never leave your machine.
