How to use Docker Compose Validator & Normalizer

Parse Compose YAML, summarize services, flag missing build/image fields and risky privileged mode, and emit deterministic YAML.

1. Paste, type, or drag and drop a supported text file into the input area.
2. Review the input and the clearly labeled output behavior.
3. Select “Run tool” or press Ctrl/Command + Enter, then copy, download, or move the result back into the first input for another pass.

What the result means

A service table, actionable diagnostics, and normalized YAML.

Privacy and safety

This utility is loaded as browser code and processes your input only in this tab. OmniCastConverter has no upload endpoint and never stores your content, filenames, tokens, or secrets. Generated markup and code are shown as inert text and are never executed.

Limitations

• Everything is processed in this browser tab. Input, filenames, keys, and output are never uploaded or saved. Version-specific engine behavior, variable expansion, includes, profiles, secrets, and registry availability need Docker’s own config validation.
