YAML Sort Keys

Parse YAML, alphabetize object keys at every mapping level, then serialize readable YAML locally.

YAML

Sorted YAML

ReadyMapping/object keys are sorted recursively. Array item order is intentionally preserved.

Before using the YAML

Parse first, then choose a target format whose data model matches the job. Conversion success does not prove that an application will accept the resulting config.

Format / validateConfirm the YAML parses before migration.

Inspect structureCheck mappings, arrays, paths and scalar types.

Choose target modelTOML has tables; Properties and ENV are fundamentally string-key/value formats.

ConvertUse explicit flattening/type rules rather than hidden guesses.

Verify in contextReview application-specific schema and semantics before replacing production config.

Format Validate Tree Find path YAML → JSON JSON → YAML YAML → XML XML → YAML YAML → TOML TOML → YAML YAML → Properties Properties → YAML YAML → ENV

conversions run in the browser. The new TOML path targets common configuration syntax rather than claiming a complete TOML conformance suite; Properties nesting is an explicit WebToolArc convention, not part of Java Properties itself.

YAML sort-policy preview

Choose direction, depth and case policy, then inspect what the sorter should preserve. Sorting mappings is not the same task as extracting key paths.

Sequence order is normally meaningful and should not be silently alphabetized.

Before converting YAML

Format and validate first, inspect the parsed structure, then convert only after deciding how the target format should represent arrays, nested mappings and scalar types.

Syntax is not application validity

A YAML document can parse successfully and still be invalid for Kubernetes, Docker Compose, GitHub Actions, CI/CD, OpenAPI or another application schema.
