XML to CSV Converter
Paste XML and download as CSV. Auto-detects the row element, flattens nested structures, handles attributes. Browser-only — your XML never leaves your device.
Updated May 2026
Browser-only — XML never leaves your device. Works best on flat denormalized XML (data exports). Deeply nested hierarchical XML doesn’t map cleanly to CSV; the tool flattens with dotted-path column names.

What it does
Paste XML, get a downloadable CSV. Auto-detects the repeating row element, flattens nested fields with dotted-path column names, and handles attributes (saved as tag@attr columns). Browser-only — your XML never leaves your device, no upload, no signup.
Pairs with our JSON to CSV and CSV to Excel tools for end-to-end data conversion workflows. See the data conversion guide for the multi-step patterns.

Frequently asked questions
- What XML structures work best?
- Flat denormalized exports — invoices, customer lists, transaction logs, anything where you have a repeating element with simple child fields. Deeply nested hierarchical XML (multi-level trees with arrays inside arrays) doesn't map cleanly to CSV; the tool flattens with dotted-path columns but the result may be wide and sparse.
- How does it handle attributes vs child elements?
- Attributes become columns named tag@attr. Child elements become columns by their tag name. Repeated children get indexed (e.g. address[1], address[2]). This keeps everything addressable in CSV without losing data.
- Does it work with namespaced XML?
- Yes — namespace prefixes are preserved in column names. Strip them with find/replace in your CSV after if your downstream tools don't like them.
- Is my XML uploaded anywhere?
- No. Parsing and conversion happen entirely in your browser using the native DOMParser. No network calls, no server, no logs.

Formula
Parse XML with native DOMParser. Identify the row element: use the user-supplied CSS selector if given, else auto-detect as the first repeating child of the root. For each row, recurse depth-first collecting leaf text into a flat dictionary keyed by dotted path (parent.child.grandchild). Attributes flatten as 'tag@attr'. Repeated siblings get indexed (tag[1], tag[2]). Union of all keys across rows = CSV header set. Write CSV with RFC 4180 quoting.
What this assumes
XML is well-formed (parsererror falls back to a clear error message). Output works best for denormalized exports — invoices, customer lists, transaction logs. Deeply nested hierarchical XML with arrays-inside-arrays produces wide sparse CSVs; that’s the right answer in CSV but may not be what the user wanted. Namespace prefixes are preserved in column names; strip with downstream find/replace if needed.
