JSON to YAML

A JSON to YAML converter turns JSON into clean YAML (and toggles YAML back to JSON) on this same URL. Conversion runs in your browser with FileReader — nothing is uploaded or written to localStorage. Closing the tab drops the payload. It is a convenience converter for configs and manifests, not a merge-PDF tool and not a hosted paste bin.

Paste or drop a .json, .yaml, or .yml file, choose JSON → YAML or YAML → JSON, and convert in this tab. Nothing is uploaded. Closing the tab drops the buffer. Tabs used for YAML indentation are rejected with a clear line/column error; invalid input does not invent output.

One canonical URL — there is no /yaml-to-json/ path and no /in/ prefix. India-first SAMPLE examples use city names; the same page works globally.

Converter

JSON → YAML

Paste a JSON object or array. Drop a .json file — it stays in this tab.

Optional .json, .yaml, or .yml drop. Read with FileReader in this tab — never uploaded.

Output

How does the JSON to YAML work?

  1. 1. Paste or drop a file

    JSON for JSON → YAML; YAML for YAML → JSON. Dropped .json / .yaml / .yml files are read with FileReader in this tab — never uploaded.

  2. 2. Choose direction

    Toggle JSON → YAML or YAML → JSON on this same URL. There is no separate yaml-to-json page.

  3. 3. Convert locally

    Parsing runs in the browser (YAML 1.2 core schema, 2-space indent). Tabs for indent and syntax errors show line/column messages; invalid input leaves output empty.

  4. 4. Copy or download

    Copy the result or download .yaml / .json matching the output mode. Closing the tab drops the buffer.

Questions about JSON to YAML

Does JSON to YAML upload my file?
No. Parsing and conversion run in your browser. There is no account and no server-side converter. Dropped files are read with FileReader in this tab; we do not upload them to Page Utils or write them to localStorage. Closing the tab drops the buffer.
Is there a separate YAML to JSON URL?
No. Switch the direction to YAML → JSON on this same /file-conversion/json-to-yaml/ page. We do not publish /file-conversion/yaml-to-json/ as a second path. The toggle keeps one canonical trailing-slash URL.
Which YAML version is supported, and what about tabs?
The converter targets YAML 1.2 using the core schema (scalars, lists, mappings). Indentation defaults to two spaces. YAML forbids tabs for indentation — if your paste uses tabs to indent, you get a clear line/column error rather than a silent rewrite. Conversion stays in this tab; nothing is uploaded.
How are syntax errors shown?
Invalid JSON or YAML leaves the output empty and shows an inline error with line and column when the parser provides them. The tool does not invent a partial result. Fix the marked spot and the live conversion updates in this tab.
Is there an /in/ version for India?
No. The same /file-conversion/json-to-yaml/ URL works globally, including from India. We do not duplicate tools under a country prefix. SAMPLE examples may use Indian city names; the converter itself is format-agnostic.
Can I convert huge multi-megabyte files here?
This page is for payloads that fit comfortably in browser memory. Multi-megabyte manifests can freeze or exhaust the tab — use a local CLI for those. Closing the tab drops whatever you pasted. This is not a merge-PDF tool and not a bulk file host.
Are YAML comments, anchors, and aliases preserved?
Comments and anchors/aliases are not a guaranteed round-trip. JSON has no comment syntax, so anything you paste as JSON cannot carry comments into YAML. The converter targets YAML 1.2 core for configs and manifests — do not rely on preserving comments through JSON → YAML → JSON. Conversion stays in this tab; nothing is uploaded.
Do null, empty objects, and empty arrays round-trip?
Yes. null, {}, and [] survive both directions as valid JSON and YAML. An empty string is distinct from null. Object key order follows JSON.stringify / YAML dump behaviour in the browser — fine for configs, not a semantic diff tool. Closing the tab drops the buffer.

What else can I open?

These tools run in your browser. Page Utils does not store, upload, or write to localStorage the keys, tokens, or text you paste. Results are a convenience aid, not legal, tax, or security advice.
