JSON → YAML
FormattingRound-trip JSON into YAML with 2-space indent.
What this tool helps with
JSON and YAML model the same data; YAML just trades braces for indentation, which is why Kubernetes manifests, CI pipelines, and app config favour it for human editing. This converter round-trips JSON into YAML with a 2-space indent. The subtle part is type coercion: strings like "yes", "no", "on", and version numbers can be misread as booleans or numbers by older YAML — this conversion keeps your values intact. It runs in-page so config that contains secrets stays local.
How to use JSON → YAML
- Open the JSON → YAML page and paste, type, or generate the json input you want to work with.
- Pick the options you need so the tool can round-trip JSON into YAML with 2-space indent
- Copy the yaml result with one click and use it in your next step — terminal, editor, ticket, or anywhere else you need it.
Common uses
- Reach for JSON → YAML when you need to round-trip JSON into YAML with 2-space indent during debugging, code review, or content preparation.
- Skip installing a desktop json app — open this formatting utility on a shared machine, an iPad, or a colleague's laptop and it just works.
- Bookmark or share the page when you and your team keep coming back to the same json, yaml, convert, and transform workflow.
FAQ
Why did my string "no" turn into false somewhere?
The YAML 1.1 spec treats yes/no/on/off as booleans, so unquoted they coerce. The fix is quoting; this tool emits values that survive a round trip. Many parsers still use 1.1 semantics, so be deliberate with such strings.
Does YAML preserve key order?
Mapping key order is not significant in the data model, but this conversion preserves the order from your JSON so diffs stay readable.
Can YAML represent everything JSON can?
Yes — YAML is a superset, so any JSON document is valid YAML. The reverse is not true: YAML anchors, comments, and multi-document streams have no JSON equivalent.
