Validators

Catch syntax errors before deploy

Invalid YAML or XML in a Kubernetes manifest, CI pipeline, or config file can cause silent failures or production outages. Validators catch syntax problems early — before they reach staging or production environments.

While JSON validation lives in the JSON Tools category, it pairs naturally with YAML and XML validators when you work across multiple config formats in the same project.

YAML validator

YAML's indentation-sensitive syntax makes typos common: mixed tabs and spaces, missing colons, or unclosed quotes. The YAML Validator reports the line and nature of each error so you can fix Ansible playbooks, GitHub Actions workflows, and Docker Compose files quickly.

XML validator

The XML Validator checks well-formedness — mismatched tags, invalid characters, and malformed declarations — with line-level feedback. Use it for SOAP payloads, SVG snippets, Maven POM files, and any XML-based integration before sending to downstream systems.

Validate locally, keep data private

Config files often contain database connection strings, API endpoints, and internal hostnames. TOOLS WORLD validators process everything client-side, so sensitive infrastructure details never traverse the network during validation.
