Do YAML anchors survive the conversion?

Anchors and aliases expand into normal JSON objects because JSON lacks a native anchor syntax. The tool lists detected anchors so you can document the merge behavior.

Is there a size limit?

Typical configuration files of several megabytes convert instantly. For huge documents consider command line tooling so your browser does not run out of memory.

Can I edit the output before sharing?

Yes. Both panes stay editable. After making changes, the share link updates automatically so collaborators see the revised state.

Browser tool

JSON ⇄ YAML Converter

Switch between JSON and YAML formats while preserving structure.

Convert between JSON and YAML instantly, keep tabs on anchors and merges, and generate shareable URLs that preserve both panes. All processing happens client-side for privacy.

Key points

Bidirectional conversion

Switch between JSON → YAML and YAML → JSON without reloading. Share links capture both panes so teammates land on the same state.

Anchors & merges surfaced

When YAML anchors or aliases are detected the tool highlights them so you understand when merge keys expanded in the JSON output.

Everything stays local

Conversions, beautification, and file imports run entirely in your browser. Nothing uploads to a server, keeping sensitive configs private.

How to use this tool

Step 1
Choose your direction
Pick JSON → YAML or YAML → JSON depending on the payload you have. The active mode sets which pane is treated as the source.
Step 2
Paste or drop your document
Paste text directly, drag in .json/.yaml files, or tweak an existing share link. The tool updates the URL automatically for sharing.
Step 3
Convert, beautify, and download
Run Convert for a fresh output, use Beautify to tidy formatting, then copy or download the result when you are happy with it.

JSON has no anchor syntax, so YAML anchors expand into duplicated structures during conversion. Review the anchor notice above the editor when working with complex configs.
