Frequently Asked Questions

Yes, absolutely. The conversion process runs entirely in your web browser using JavaScript. No data is ever sent to our servers.
Yes, since the processing is done locally, the file size limit depends on your browser's memory, but generally, files up to several megabytes handle smoothly.
Standard JSON does not support comments, so YAML comments are lost during conversion. However, converting from JSON to YAML works perfectly.
When enabled, the tool automatically detects which format you are typing in and converts it to the other format in real-time without needing to click a button.
The tool will highlight the specific line and column of the error, and the conversion output will pause until the syntax is fixed.
Yes, both YAML lists and JSON arrays are fully supported, including nested transformations.
