Convert freely between JSON / YAML / XML / CSV — with validation, direction swap, and download
• Convert: pick a source and target format, then click Convert — any combination of JSON / YAML / XML / CSV works.
• Swap direction: flip source / target in one click and reuse the last output as the new input.
• CSV uses the first row as a header to build an array of objects; XML keeps attributes (@_ prefix).
• Memory: when on, your last input is saved to local storage.
