What XML shape converts cleanly to CSV?

CSV is inherently tabular, so this works best on XML that represents a flat or shallow list of records, an ... feed, an export of rows, that kind of shape. Deeply nested or highly irregular XML will still convert, but the resulting columns may be harder to read.

How does the converter turn a tree structure into flat rows?

It first converts the XML to JSON (the same conversion the XML to JSON Converter performs), then flattens that JSON into rows with dotted or bracketed column names representing nested paths, the same flattening logic used by the JSON to CSV converter.

What happens to XML attributes in the CSV output?

Attributes are represented as @-prefixed keys during the intermediate JSON step, so they become their own column (e.g. an id attribute becomes an "@id" column) rather than being dropped.

What happens if my XML isn't well-formed?

Conversion requires valid XML as its starting point, so a syntax error is reported with its exact line and column before any CSV is produced, the same error reporting used by the XML Validator.

Will this handle a very large XML export?

Yes, up to whatever your browser can comfortably hold in memory, since the whole document is parsed and flattened client-side. Very large files (tens of megabytes) may take a moment to process.

XML to CSV Converter - Convert XML to CSV Online

Overview

Introduction

XML exports from legacy systems, RSS-style feeds, and enterprise APIs are common, but almost nobody wants to review a list of records by scrolling through nested markup. This converter turns that XML into CSV rows you can open directly in a spreadsheet.

It's built for the everyday case: an XML feed or export lands in your hands, and what you actually need is a table.

What Is XML to CSV Converter?

An XML-to-CSV converter that flattens an XML document's element and attribute structure into rows of comma-separated values, with a header row naming each column.

Under the hood it's a two-step pipeline: XML is first converted to an equivalent JSON structure, then that JSON is flattened into CSV, reusing the same conversion logic that powers the standalone XML to JSON and JSON to CSV converters.

How XML to CSV Converter Works

Your XML is parsed and mapped onto plain JSON the same way the XML to JSON Converter does: elements become keys, attributes become @-prefixed keys, and repeated sibling tags become arrays.

That JSON value is then flattened into CSV rows, nested paths become dotted or bracketed column names, and the result is serialized with a header row followed by one row per record.

When To Use XML to CSV Converter

Use it when you've received an XML export, feed, or API response and need to review, filter, or share it as a spreadsheet.

It's also useful for quickly sanity-checking how many records an XML document actually contains, a CSV's row count makes that obvious at a glance.

Often used alongside CSV to XML Converter, XML to JSON Converter and XML to TSV Converter.

Features

Advantages

Runs entirely client-side, so XML with real customer or business data never leaves your browser.
Handles nested elements and attributes by flattening them into clearly named columns.
Reuses the same battle-tested XML-to-JSON and JSON-to-CSV logic as the standalone converters, so behavior is predictable.
Produces a header row automatically, ready to paste into a spreadsheet or open as a .csv file.

Limitations

Works best on shallow, list-like XML; deeply nested or highly irregular documents produce correspondingly complex column names.
Mixed content (text interleaved with child elements) doesn't have a clean tabular representation and may be simplified.
Doesn't infer or enforce column types; every CSV cell is text.

Examples

A simple record list

Input

<users><user><id>1</id><name>Ada</name></user><user><id>2</id><name>Alan</name></user></users>

Output

id,name
1,Ada
2,Alan

Each <user> element becomes a row, and its child elements become columns.

An attribute becomes its own column

Input

<items><item id="1"><label>Widget</label></item></items>

Output

@id,label
1,Widget

The id attribute survives the XML-to-JSON step as "@id" and becomes a dedicated column.

An unclosed tag is caught before conversion

Invalid input

<items><item>value</items>

Parser error

Unclosed tag <item> at line 1, column 28

Well-formedness is checked first, exactly as the XML Validator would report it.

Corrected version

<items><item>value</item></items>

Best Practices & Notes

Best Practices

Use this on record-shaped XML (a repeated element under one wrapper) for the cleanest CSV output.
Check the header row against what your spreadsheet or downstream tool expects before importing.
Run the XML Validator first if you're unsure whether the source document is well-formed.

Developer Notes

`xmlToCsv` (in this category's `lib/xml-to-csv-converter.ts`) is a thin composition: it calls `xmlToJson` from the JSON category, then pipes that output into `jsonToCsv`, also from the JSON category. No new parsing or flattening logic lives in the XML category itself, keeping a single source of truth for both the tree-to-JSON mapping and the JSON-to-tabular flattening.

XML to CSV Converter Use Cases

Turning an XML export from a legacy system into a spreadsheet-ready CSV
Reviewing an RSS or API feed's records as a table instead of scrolling raw markup
Sharing XML data with a non-technical teammate who works in spreadsheets
Quickly counting records in an XML document via the resulting row count

Common Mistakes

Feeding deeply nested XML and expecting simple, human-friendly column names, flattening reflects the actual nesting depth.
Assuming column order is preserved from the source XML when downstream tooling reorders or re-sorts columns.
Forgetting that every CSV cell is plain text, so numeric- or boolean-looking values may need re-parsing downstream.

Tips

Pair with the CSV to XML Converter to check what a round trip does to your specific document.
Use the XML to JSON converter first if you want to inspect the intermediate structure before it's flattened.
Upload a .xml file directly instead of copy-pasting if the document is large.
