Frequently asked questions
What happens with several YAML documents?
Documents separated by --- become a JSON array, one item per document.
How are errors reported?
The converter shows the line and column of the first error, such as duplicate keys or bad indentation.
Is my data uploaded?
No. The conversion runs in your browser and nothing is sent anywhere.
Are my files uploaded anywhere?
No. YAML to JSON Converter runs entirely in your browser. Your files are processed on your device and are never sent to a server.
Is there a file size limit?
No fixed limit. The only limit is your device's memory. Very large files work best in a desktop browser.
Is YAML to JSON Converter really free?
Yes. There's no account and no watermark. A short optional ad, or a 20-second wait, unlocks each download. That's how we keep it free.
