Document format · .xml
XML carries structured data where contracts matter: sitemaps, RSS feeds, Office documents, SOAP APIs, and config files. Verbose but self-describing — convert XML to JSON for modern APIs or to CSV for spreadsheets.
Every tool runs in your browser — files never leave your device. Badges say exactly what each tool does with XML.
Use XML to JSON — it maps elements and attributes to JSON locally, ready to paste into modern code.
Usually one unescaped ampersand, mismatched tag, or bad encoding declaration. Run it through the XML formatter first — it pinpoints the break.
JSON, almost always — smaller, faster, native to JavaScript. Keep XML only where a schema contract or legacy system demands it.
Completely. Parsing and conversion run in your browser; data never uploads.
