How to use this tool
- Choose a direction: JSON → YAML or YAML → JSON.
- Paste your data.
- Click Convert, then copy the result — or swap it back in to convert the other way.
Frequently asked questions
- What YAML features are supported?
- Standard YAML 1.2: nested mappings and sequences, strings, numbers, booleans, and null. Anchors/aliases and multi-document files are not expanded into JSON, since JSON has no equivalent concept.
- Why would I convert JSON to YAML?
- Many config formats — Kubernetes manifests, GitHub Actions workflows, Docker Compose, CI pipelines — use YAML for its more readable, less punctuation-heavy syntax, while APIs and scripts often produce or expect JSON.
- Does key order or formatting survive the round trip?
- Key order is preserved. Comments in YAML are not preserved, since JSON has no way to represent them — if you convert YAML with comments to JSON and back, the comments will be gone.
- Is my data uploaded anywhere?
- No — the conversion happens entirely in your browser. Nothing is uploaded.
How GetByteRush compares
Most free tools for this online work the same way: you upload your file to their server, wait, then download the result — which means your file (and often your email, for a "free" account) sits on someone else's infrastructure. Here's the actual difference:
| Feature | GetByteRush | Typical online tools |
|---|---|---|
| Data ever leaves your device | No — converted in this tab | Yes, uploaded to process |
| Preserves key order | Yes | Varies |
| Account required | Never | Often, past a certain usage level |
