Frequently asked questions

Can I recover my documents after closing the page?

Documents are saved automatically in this browser and restored when you return. Closing a document with X deletes it. Browser cleanup can also remove saved work; download important results or export your workspace.

Are JSON numbers rounded in YAML output?

The converter preserves JSON number text rather than silently rounding it; review the YAML representation before use.
