YAML to JSON FAQ
Are YAML comments preserved?
No. JSON does not support comments, so any YAML comments (lines starting with #) are stripped during conversion. The data itself is fully preserved.
What YAML features are supported?
The converter supports all standard YAML 1.2 features: mappings, sequences, scalars, multi-line strings, anchors, and aliases. Flow style and block style are both handled.
Is the output valid JSON?
Yes. The output is always valid, well-formatted JSON. You can control the indentation level (2, 4, or 8 spaces) and copy or download the result.
Is my data safe?
All conversion happens in your browser using JavaScript, and this tool doesn't send your configuration files to our servers.
Need to share config files securely?
Don't paste secrets from your YAML/JSON configs into chat or email. Use CredenShare to deliver them with end-to-end encryption and automatic expiration.
