YAML / JSON

Convert YAML ↔ JSON with format and validate—local, no signup.

YAML

JSON

Format, validate, query, compare, and convert JSON, YAML, TOML, XML, CSV, and typed models.

How to use & FAQ

DevOps and backends mix YAML configs with JSON APIs. Tools Ku converts in-browser so tokens and kube secrets never hit a server.

Pair with JSON Formatter and JSON Diff for a full config toolkit.

Is my config uploaded?▾

No—all conversion is local.

Why conversion fails?▾

Invalid JSON or YAML indentation/quotes—check the error hint.

Comments preserved?▾

YAML comments drop when becoming JSON; JSON has no comments.

Large files?▾

Browser memory limits—CLI for very large configs.

Number typing surprises?▾

YAML may parse 001 differently—validate critical fields.

Signup?▾

No.
