FAQ
Common questions about the JSON to YAML converter.
How do I convert JSON to YAML?
Paste your JSON object or array in the editor and press Convert to YAML. The clean YAML output appears below, ready to copy or download.
Is my data uploaded to a server?
No. All processing happens entirely in your browser with JavaScript. Your data never leaves your device.
Are nested JSON objects and arrays handled?
Yes. Nested objects and arrays are converted into indented YAML mappings and sequences, and strings that need quoting are quoted automatically.
Can I convert a JSON array?
Yes. Arrays are converted into YAML lists with the correct indentation, including arrays of objects.
Can I download the YAML as a file?
Yes. Use the Download button after converting to save the output as an output.yaml file.
Will my YAML stay valid?
The converter quotes keys and values that contain special characters, leading/trailing whitespace, or look like booleans/numbers, so the output loads correctly in other tools.
