How to use it
- Paste the YAML.
- Fix any error at the line it names.
- Copy or download the JSON.
Nothing you paste leaves this page
The conversion runs in this browser tab. Nothing is sent to Sellstamp or anyone else, which matters for configuration files, customer exports and tokens.
Safe parsing
YAML is parsed by the yaml library, which never runs code from the document and limits aliases, so a “billion laughs” file cannot expand into gigabytes. Comments are dropped, since JSON has none.
Questions
Why is “no” turned into false?
It is not, in YAML 1.2, which this tool uses: only true and false are booleans.
Where are my comments?
JSON cannot hold comments, so they are dropped.
What does the error mean?
It names the line and column where the YAML stopped making sense: often a wrong indent or a tab.
Can it handle several documents in one file?
It reads the first document. Split the file at --- to convert the others.
