About this tool
What you can do with YAML editor
The YAML editor parses configuration text directly in your browser, identifies syntax problems and produces consistently indented output. You can copy the formatted result or download it as a YAML file without uploading configuration data to Gainup.
Tips for better results
- Use spaces instead of tabs for indentation.
- Quote values that could be interpreted as booleans, numbers or dates when they must remain strings.
- Avoid pasting production secrets on shared devices even though processing stays local.
