Can Notepad++ convert XML to CSV?

Not directly — Notepad++ is a text editor, not a converter. You can open an XML sitemap in it to inspect the structure, but turning it into CSV requires either find-and-replace gymnastics with regular expressions (fragile, breaks on escaped characters) or a plugin like XML Tools. The cleaner path is a dedicated converter: paste the sitemap URL or file content into an online tool and download CSV directly. The xmlsitemapmaker.com converter handles the parsing correctly, including entity escaping, namespaces and CDATA blocks that Notepad++ regex would miss. If you really want a manual approach, Excel's Data → From XML works for small simple sitemaps without needing any plugin.
