Description
Validate TOML strings and convert to JSON.
How to Use
1
1. Send a POST request with the `data` field containing your TOML string.
2
2. If `valid` is `true`, the `as_json` field contains the parsed data as JSON.
3
3. If `valid` is `false`, the `error` field describes the problem.
About This Tool
TOML Validator checks whether a string is valid TOML and returns the parsed result as JSON. Useful for validating `pyproject.toml`, `Cargo.toml`, or any TOML config before deployment.
Why Use This Tool
- Config validation — Verify `pyproject.toml`, `Cargo.toml`, or Hugo config files
- TOML to JSON conversion — Convert TOML data for JSON-based workflows
- CI/CD checks — Validate config files in pipelines before deployment
