How to use JSON to YAML

Paste your JSON
Paste JSON, or open or drop a .json file. It’s checked and converted as you type.
Choose the indent
Pick 2 or 4 spaces. Keys stay in their order and numbers keep the digits you wrote.
Copy or download
Copy the YAML, or download it as a .yaml file.

Safe for every YAML reader
Strings that a YAML reader could mistake for something else, like yes, on, 007 or 2024-01-01, are quoted, so they stay text in old and new parsers alike.
Nothing reordered or rounded
Keys come out in the order you wrote them, and numbers like 1.10 or long IDs keep every digit.
Errors you can fix
Invalid JSON shows the line and column of the mistake with a hint, like a trailing comma or a missing quote.
Private by design
Your JSON is converted on your device and never uploaded, so secrets in config files stay with you.

Yes. A top-level array becomes a YAML list, and a lone value like 42 or "hello" becomes a one-line YAML document.

YAML reads unquoted yes, no, on, off, numbers and dates as booleans, numbers or dates. Quoting them keeps them as the text they were in your JSON.

No. Keys stay in their order, even ones like "2" and "1", and numbers are written exactly as they appear in the JSON.

No. Standard JSON has no comments, so the YAML has none either. Add them after converting with a # at the start of a line.

Files up to 50 MB can be opened. Very large results are shown cut short on the page, but copy and download include all of it.
