Frequently asked questions

Can I convert XML to CSV without an internet connection?
Yes. After the page loads, all XML parsing and CSV generation run inside your browser's local JavaScript engine. You can disconnect from the internet and still complete the conversion. No server round-trip is ever needed.
How does offline XML to CSV conversion work technically?
The conversion engine is bundled as a client-side JavaScript module. When you trigger a conversion, the browser reads your XML input from memory and writes the CSV result directly to a Blob URL, entirely on-device, with no network calls.
Does the offline XML to CSV tool save any data to my browser cache?
No XML data is written to localStorage, IndexedDB, or any other persistent browser storage. Only the page's static JavaScript assets are cached for offline use; your actual file content is discarded the moment you navigate away.
Will the offline XML to CSV converter work on a mobile device?
Yes. The converter uses standard Web APIs that are fully supported in modern mobile browsers. You can load a XML file from your phone's storage and download the CSV output, all without a data connection after the initial page load.
Are there any differences between the offline and online versions of the XML to CSV tool?
There is no separate "online" version. The tool is always browser-based. The offline capability simply means the conversion engine itself does not require an active connection. The feature set, output format, and CSV fidelity are identical regardless of connectivity.
