Frequently Asked Questions

Common questions about this tool.

Can I convert Docker Compose or Kubernetes YAML to JSON? ▼

Yes! Paste your Docker Compose (`docker-compose.yml`) or Kubernetes deployment manifest into the input editor to convert indentation-based YAML structures into valid JSON objects.

Can I convert JSON back into YAML format? ▼

Yes! Toggle the direction in the workbench header to convert JSON object payloads into clean, 2-space indented YAML configuration files.

How are indentation and spaces handled in YAML parsing? ▼

YAML relies strictly on space indentation (tabs are disallowed by the YAML spec). The converter normalizes indentation and validates key-value structure.

Are YAML comments preserved when converting to JSON? ▼

Standard JSON does not support comments (`#`), so comments present in the input YAML are omitted during JSON export.

Is client-side YAML conversion secure for secret config files? ▼

Yes. 100% of conversion logic runs locally inside browser JavaScript memory. Sensitive environment variables, secrets, and API keys are never uploaded.
