Frequently Asked Questions
QIs JSON to YAML conversion lossless?
Yes for all standard JSON types. JSON objects become YAML mappings, arrays become YAML sequences, strings, numbers, booleans and nulls all have direct YAML equivalents. JSON key order is preserved.
QCan I convert minified or single-line JSON?
Yes. Paste any valid JSON — formatted or minified — and the converter will parse it and produce properly indented YAML output regardless of how the input was formatted.
QCan I convert back from YAML to JSON?
Yes. Use the swap button (⇄) in the toolbar to reverse the direction and convert YAML back to JSON in the same tool.
QCan I convert to other formats besides YAML?
Yes. Use the 'To' dropdown to switch the output format to XML, TOML, CSV, SQL INSERT, HTML Table or Markdown. The URL updates automatically for each pair.
QIs my data sent to a server?
No. The conversion runs entirely in your browser using js-yaml. Nothing you paste is ever transmitted to any server.
