Frequently asked questions
Are YAML comments preserved?
No, comments are lost when converting to JSON. JSON to YAML uses a 2-space indent and keeps the structure. Split multi-document YAML separated by --- before converting.
Do my files get uploaded to a server?
No. All 12 tools run inside your browser, so files never leave your device. Closing the tab ends the session.
