FAQs

            
JSON converter and data formatter questions

            
How do I convert JSON to XML online?
Paste JSON into the source editor, keep the JSON XML tab selected, and use Convert or Live preview to generate validated XML output.

            
Can I convert XML back to JSON?
Yes. Use Swap Direction on the JSON XML tab to convert XML into structured JSON.

            
Does the frontend expose the parser?
No. JavaScript only sends editor content to WordPress AJAX and updates the interface. Conversion functions run securely on the server.

            
Can JSON arrays become CSV?
Yes. Arrays of objects are flattened into CSV headers and rows, including nested keys with dot notation.

            
Is YAML support full specification YAML?
The built-in parser supports common key value YAML used in quick conversions. Complex anchors and custom tags should be handled by a dedicated YAML parser.
