YAML Tools

Format, validate, merge and convert YAML in your browser.

YAML Formatter Re-prints a YAML document with consistent indentation and quoting, and is honest that comments do not survive the trip.
YAML Key Sorter Sorts mapping keys alphabetically at every level, leaving sequence order alone, so two configurations can be diffed meaningfully.
YAML Merge Merges an overlay document onto a base document and lists every value the overlay replaced.
YAML Path Finder Lists every leaf path in a configuration with its type and value, so a single setting can be named exactly.
YAML to JSON Converts YAML to JSON, and points out the type surprises that conversion exposes.
YAML to XML Converts YAML to XML, letting you name the root and the element used for sequence items.
YAML Validator Checks that a YAML document parses, and names the line where it stopped making sense.
