Frequently asked questions

Is the structure preserved exactly?+

Yes. Objects, arrays, strings, numbers, booleans and null map directly to their YAML equivalents, so the data round-trips losslessly.

How is the YAML formatted?+

Two-space indentation with no forced line wrapping, which keeps long string values on a single line and stays readable.

Are my files uploaded?+

No. The conversion runs entirely in your browser on your device — your JSON is never uploaded.
