Question 1

Does it convert both directions?

Accepted Answer

Yes. Switch between JSON to YAML and YAML to JSON with a single click.

Question 2

Which YAML version is supported?

Accepted Answer

It uses a standard YAML 1.1/1.2-compatible parser, handling mappings, sequences, scalars, and multi-document basics common in config files.

Question 3

Why did my YAML fail to convert?

Accepted Answer

YAML is indentation-sensitive. Inconsistent indentation, tabs mixed with spaces, or invalid syntax will be reported so you can fix it.

Question 4

Can I control indentation?

Accepted Answer

Yes. Choose 2 spaces, 4 spaces, or tabs, and optionally sort keys alphabetically in the output.

Question 5

Is my data uploaded?

Accepted Answer

No. Conversion runs entirely in your browser; nothing is sent to a server.
