CSV to XML Converter

Parses CSV (honoring quoted fields, embedded commas, and escaped quotes) and wraps each row as a <row> element under a single <rows> root, producing well-formed XML from a spreadsheet export. A free online tool from Staaarter, right in your browser.

Overview

Introduction

A spreadsheet export or CSV data dump is easy to work with by eye, but plenty of downstream systems, config loaders, and legacy APIs still expect XML. This converter closes that gap without a server round trip, wrapping your rows in valid, well-formed markup.

It's the tool to reach for when you've exported data as CSV but the next step in a pipeline needs XML input.

What Is CSV to XML Converter?

A CSV-to-XML converter that parses delimited rows (honoring RFC 4180 quoting) and maps each one onto a <row> element, using the header row's values as the child element tag names within every row.

Because CSV has no single root the way XML requires, every <row> is nested under one wrapping <rows> element, giving the document exactly the one root XML mandates.

How CSV to XML Converter Works

Your CSV is parsed the same way the CSV to JSON converter parses it: quoted fields, embedded delimiters, and escaped quotes are all handled per RFC 4180, producing an array of row objects keyed by header value.

That array is then passed through the JSON to XML converter with the root name forced to rows and each item tagged as row, so the intermediate JSON representation and the XML output stay consistent with the rest of this category's conversion tools.

When To Use CSV to XML Converter

Use it when a downstream system, config loader, or legacy API requires XML but your data currently lives in a CSV export.

It's also useful for quickly previewing what a spreadsheet's rows would look like as XML before writing a permanent import mapping.

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

Features

Advantages

  • Runs entirely client-side, so CSV data with real business or customer information never leaves your browser.
  • Handles RFC 4180 quoting correctly, so commas and newlines inside quoted fields don't corrupt the row structure.
  • Produces well-formed, single-root XML automatically, no manual wrapping required.
  • Reuses the same CSV-parsing and JSON-to-XML logic as this category's other conversion tools, so behavior is predictable.

Limitations

  • Column header names that aren't valid XML tag names fall back to a generic item tag.
  • Every value becomes an XML text node; there's no type inference (numbers and booleans stay as plain text content).
  • The <rows>/<row> wrapping is fixed, use the JSON to XML Converter separately if you need a different root or item tag name.

Examples

A simple CSV table

Input

id,name
1,Ada
2,Alan

Output

<?xml version="1.0" encoding="UTF-8"?>
<rows>
  <row>
    <id>1</id>
    <name>Ada</name>
  </row>
  <row>
    <id>2</id>
    <name>Alan</name>
  </row>
</rows>

Each data row becomes a <row> element, with header values as child tag names.

A quoted field with an embedded comma

Input

id,name
1,"Smith, John"

Output

<?xml version="1.0" encoding="UTF-8"?>
<rows>
  <row>
    <id>1</id>
    <name>Smith, John</name>
  </row>
</rows>

The comma inside quotes is treated as part of the value, not a field separator.

An unterminated quote is reported, not guessed at

Invalid input

id,name
1,"Ada

Parser error

Unterminated quoted field at line 2, column 4

Parsing stops at the exact position the missing closing quote would have been expected.

Corrected version

id,name
1,"Ada"

Best Practices & Notes

Best Practices

  • Include a header row, its values become the XML child element names for every row.
  • Keep header names as valid XML identifiers if you need them preserved as tag names exactly.
  • Run the CSV through a validator or spreadsheet check first if you're unsure it's well-formed CSV.

Developer Notes

`csvToXml` (in this category's `lib/csv-to-xml-converter.ts`) composes `csvToJson` from the JSON category with `jsonToXml`, forcing `rootName: "rows"` and wrapping the parsed array under a `row` key before conversion. No CSV-parsing or XML-serialization logic is duplicated here, both come from existing, shared implementations.

CSV to XML Converter Use Cases

  • Feeding a CSV export into a legacy system or API that only accepts XML
  • Converting a spreadsheet of data into an XML test fixture
  • Previewing an XML shape for CSV data before writing a permanent import mapping
  • Migrating tabular data into an XML-based configuration format

Common Mistakes

  • Omitting the header row, since column names are taken directly from the first CSV row.
  • Expecting a custom root or item tag name, the wrapping is fixed as <rows><row>.
  • Assuming numeric or boolean-looking CSV values become typed XML content; everything is text.

Tips

  • Pair with the XML to CSV Converter to check what a round trip does to your specific data.
  • Use the XML Prettifier afterward if you want different indentation than the default.
  • Quote any field containing a comma, newline, or quote character before pasting, per standard CSV rules.
