How do I convert an XML file to Excel (.xlsx)?

Open AnyTool XML to Excel, drop your .xml file in, and it auto-detects the repeating record element, flattens the nested structure into rows and columns, and builds a real .xlsx workbook you can download. Attributes, namespaces and CDATA are handled, you can preview the table before exporting, and everything runs in your browser — the file is never uploaded.

Auto-detects the repeating element so each record becomes one row
Flattens nested XML into dotted columns (order.customer.name) automatically
Keeps attributes, namespaces and CDATA — your choice of how to map them
Writes a genuine .xlsx with styled, frozen headers and auto-fit columns
100% in your browser via ExcelJS — no upload, no signup, works offline

What is

XML to Excel Conversion

XML to Excel conversion turns hierarchical XML data into a flat spreadsheet by choosing a repeating element as the row unit, then mapping each child element and attribute to a column. Because XML is a tree and a worksheet is a grid, nested branches are flattened — typically with dot-notation column names — so the relationships are preserved as far as a two-dimensional table allows, and the result is saved in the Office Open XML .xlsx format.

Frequently Asked Questions

AnyTool XML to Excel reads the file with the browser File API, parses it with the built-in DOMParser, and writes the workbook locally with the ExcelJS library. Nothing is sent to a server, there is no account or tracking, and the page keeps working offline after the first load — which matters when the XML contains private or regulated data.

No. The XML is parsed and the .xlsx is built entirely in your browser, so the file never leaves your device.

After you pick the repeating record element, each record is flattened: a nested branch such as order › customer › name becomes the column order.customer.name, attributes become their own columns under a prefix you choose (@, _ or -), and when the same child tag repeats inside one record it is indexed (item[0], item[1]). The header row is the union of every field seen across all records, so sparse data still lines up correctly.

It flattens nested elements into dotted column names like parent.child, and repeated children get an index suffix.

The converter uses ExcelJS to write the Office Open XML format that Excel, Google Sheets, LibreOffice and Numbers open natively. You get a real worksheet with a styled, frozen header row and auto-fit column widths, and you can optionally split each repeating element type onto its own sheet for a multi-sheet workbook.

It is a genuine .xlsx workbook with styled headers, frozen panes and auto-fit columns — not a renamed CSV.

Because it works on any well-formed XML without needing a schema, it converts generic data exports as well as common XML-based formats — RSS and Atom feeds, OPML outlines, KML and GPX geodata, plist and SVG — and structured feeds such as product catalogs. Files up to roughly 50 MB are supported, and you can also load XML from a URL when the source allows cross-origin requests.

Detailed Explanation

Methodology

How the XML to Excel Converter Works

AnyTool XML to Excel performs the whole conversion in the browser. The file is read with the File API and parsed by the native DOMParser, then the tool walks the tree to find repeating element paths and offers the most frequent one as the record unit, so each matching node becomes a row. Inside each record, child elements are flattened into dotted column names (parent.child), attributes are emitted as their own columns under a configurable prefix (@, _ or -), and same-tag siblings are indexed (item[0], item[1]). The header row is the union of every field seen across all records, and the workbook is written with the ExcelJS library directly to the Office Open XML .xlsx format.

Repeating record element auto-detected from tree structure
Nested elements flattened to dotted columns; attributes prefixed
Header is the union of all fields, so sparse records still align
Real .xlsx written client-side with ExcelJS — no server round-trip

How It Works

Workbook Output, Styling and Multi-Sheet Mode

The output is a genuine .xlsx that Excel, Google Sheets, LibreOffice and Numbers open natively — not a renamed CSV. Headers can be styled (filled background, bold white text) and frozen, and column widths can auto-fit their content up to a cap. When several distinct element types repeat, a multi-sheet mode places each element type on its own worksheet, with sheet names sanitised to Excel rules (31 characters, no []:*/\? characters). A live preview shows the first rows and columns of the chosen record before anything is exported.

Auto-fit column widths capped for readability

Limitations

Flattening Limits and Scope

Flattening a tree into a grid is inherently lossy where hierarchy is deep or irregular: when the same child repeats inside a record it is indexed into separate columns rather than expanded into extra rows, which can widen the sheet, and one-to-many branches are denormalised onto the record row. Conversion is bounded by an input cap of about 50 MB and by browser memory, since the entire document is parsed in memory. The tool handles any well-formed XML without a schema — including RSS, Atom, OPML, KML, GPX and SVG — but it does not validate against a DTD or XSD.

A privacy-first, 100% client-side XML-to-Excel converter that turns hierarchical XML into a real .xlsx workbook without uploading anything. The file is read with the File API and parsed by the browser DOMParser, after which the tool auto-detects the repeating record element and treats each occurrence as a row. Within each record, child elements are flattened into dotted column names (parent.child), attributes are emitted as their own columns under a configurable prefix (@, _ or -), same-tag siblings are indexed, and the header is the union of every field across all records, with optional namespace stripping and CDATA handling. The workbook is written with the ExcelJS library to the Office Open XML format with optional styled and frozen headers, auto-fit column widths, and an optional one-sheet-per-element multi-sheet mode; a live preview shows the first rows before export. It accepts any well-formed XML — including RSS, Atom, OPML, KML, GPX and SVG — within a 50 MB input cap, computing everything in the browser and uploading nothing.
