Frequently Asked Questions

Is my data sent to a server when using the YAML Formatter?
No. The YAML Formatter is a fully client-side utility. All data processing, calculations, and conversions are handled locally in your browser. No input text, payloads, or keys are uploaded to any external server.
How does the conversion handle nested objects and lists?
Nested objects, dictionaries, and arrays are recursively mapped. Keys and structured data hierarchies are converted to their corresponding native representations in the target format.
Are code comments preserved during conversion?
Formats like JSON do not support comments. Therefore, any inline or block comments in your XML, YAML, or TOML files will be removed when converting to JSON.
What happens if my source payload has syntax errors?
The parser will highlight the validation error and pinpoint the exact line and character position where the syntax mismatch was detected, allowing you to troubleshoot.
Does the YAML Formatter store history or cache my inputs?
No. The application runs entirely in browser memory. Once you refresh the tab, navigate away, or close the window, all inputted details, logs, and outputs are completely cleared.
Is the YAML Formatter compatible with mobile devices?
Yes. The interface is optimized to be fully responsive. You can perform calculations, conversions, and formats on all modern mobile, tablet, and desktop web browsers.
Does the YAML Formatter work offline?
Yes. Once loaded, all code and assets required to run the YAML Formatter reside in your browser cache, enabling offline use without an active network connection.
