YAML ↔ JSON Converter

yamljsonconverterconfigdevops

Updated May 4, 2026

Paste YAML to get formatted JSON, or paste JSON to get clean YAML — with a one-click direction swap. The converter handles strings, numbers, booleans, null, arrays, and deeply nested objects.

A pure client-side implementation with no external dependencies. Inline comments are stripped on YAML→JSON conversion. Coverage notes clearly state what's not handled (anchors, multi-document YAML, block scalars). Nothing is sent to a server.

Coverage notes

  • Handles strings, numbers, booleans, null, arrays, and nested objects
  • YAML→JSON strips comments; inline comments on value lines are removed
  • Complex YAML features (anchors, multi-doc, block scalars) are not supported
  • Everything runs client-side — no data leaves your browser
