About YAML Validator
Validate your YAML syntax instantly to prevent errors in your configuration and deployment files. Our validator identifies common issues like improper indentation, missing colons, and syntax errors, helping you ensure your YAML is clean and deployable.
How to Use
- Enter or paste your YAML content into the input field.
- Click 'Validate YAML' to start the syntax check.
- Look for the 'Valid YAML!' message to confirm your code is correct.
- If errors are found, use the line-specific feedback to fix your syntax issues.
Common Use Cases
- Pre-validating Kubernetes or Docker configuration files before deployment.
- Checking the syntax of CI/CD configuration files (e.g., GitHub Actions, GitLab CI).
- Debugging complex, nested YAML structures to find subtle indentation errors.
Technical Details
Uses the js-yaml library to parse the input. It captures parsing exceptions to provide detailed error reports, including line numbers and context.
Frequently Asked Questions
- Why is indentation so important in YAML?
- In YAML, indentation (using spaces, not tabs) defines the structure of the data. Incorrect indentation is the most common cause of invalid YAML.
- Is there a size limit for validation?
- The validator can handle very large files, although extremely complex nested structures may take a few moments to process.
