Convert XML to CSV in Seconds

XML feeds and exports are common wherever systems talk to each other automatically — supplier catalogs, order feeds, SOAP responses — but most spreadsheets, databases, and bulk-import tools only accept flat CSV rows, not nested tags and attributes. Converting to CSV turns that repeating XML structure into the plain table those systems already expect, with column headers pulled straight from the element and attribute names.

This conversion is most useful the moment an XML feed needs to reach a tool that has no XML support at all — a bulk-upload form on an e-commerce platform, a spreadsheet a non-technical teammate needs to skim, or a database's CSV import wizard. Since CSV can't represent nesting, the flattening happens automatically: attributes and simple child elements become their own columns, while any array of nested values gets joined into a single semicolon-separated cell so no data silently disappears.

Because the parsing and flattening both happen using your browser's own XML parser running inside the tab, an XML feed that might carry order details, product data, or other business records is never uploaded anywhere during the conversion. It's read, walked, and rewritten as CSV locally, then handed straight to your downloads folder.

CSV is a flat, tabular format — every row has to have the same shape, and there's no way to nest one record inside another. XML has no such restriction: per the W3C's XML 1.0 specification (read the XML 1.0 spec), elements can nest arbitrarily deep and repeat freely, which is exactly what makes flattening XML into CSV a decision-making process rather than a mechanical one. This tool starts by finding the element that repeats under the same parent — the clearest signal that it represents one record per occurrence — and uses each repeated element's children and attributes as that record's columns.

Only the structure hanging off that one repeating element makes it into the CSV. If the document has several different repeating elements side by side, or nests one repeating group inside another, only the first one found becomes the row source — the rest either gets flattened into a single cell as JSON text or dropped from that record entirely. Per RFC 4180, the CSV specification (read RFC 4180), a CSV row is just a fixed sequence of comma-separated fields, so there's no way to represent a genuinely hierarchical relationship — like an order containing several line items, each with its own nested attributes — without losing the tree structure that connected them in the source XML.
