How do I convert a CSV file to XML?

Drop a CSV (or TSV) file into AnyTool CSV to XML, name the root and row elements, and choose for each column whether it becomes a child element or an attribute. It parses the file with a full RFC 4180 reader, escapes special characters, and shows the XML live as you type. The whole conversion runs in your browser, so your file is never uploaded.

  • Custom root and row element names (e.g. <data> / <record>)
  • Per-column toggle: write each field as an element or an attribute
  • CDATA-safe output, XML declaration, namespace and 2/4-space indent
  • Empty-cell policy (skip, empty element or xsi:nil) and UTF-8/16/ISO encodings
  • 100% in your browser — no upload, no signup, works offline

What is

CSV to XML Conversion

CSV to XML conversion turns a flat comma-separated table into a nested XML document. Each CSV row becomes a repeating element wrapped in a single root element, and each column becomes either a child element or an attribute on that row. Header names are sanitised into valid XML names — spaces and illegal characters become underscores and names that start with a digit get an underscore prefix.

Frequently Asked Questions

Yes. You set the root and row element names, and column names come from the CSV header.

AnyTool lets you type any root element (default <data>) and row element (default <record>). Each data row is wrapped in the row element, and each column uses its header as the element or attribute name. Headers are sanitised to valid XML names automatically, so a column like “Order ID” becomes Order_ID.

Yes. Click any column to toggle it between a child element and an attribute on the row.

Element mode wraps each value in its own child tag, while attribute mode places the value as name="value" on the row element — useful for identifiers and metadata. You can mix both freely, and AnyTool de-duplicates attribute names and XML-escapes every value so the output stays well-formed.

No. Parsing and XML generation run entirely in your browser, so nothing is sent to a server.

The CSV is read with the FileReader API and converted to XML in JavaScript on your device. No data is uploaded, there is no tracking, and the tool keeps working offline after the first load — which matters when the file contains customer records or other sensitive data.

A full RFC 4180 parser handles quoted commas and newlines, and values are XML-escaped or wrapped in CDATA.

AnyTool uses a proper RFC 4180 reader, so commas, quotes and line breaks inside quoted fields are parsed correctly. On output, characters like &, < and > are escaped (or, if you enable CDATA, wrapped in <![CDATA[…]]> with safe splitting of any ]]> sequence) so the resulting XML is always well-formed.

Detailed Explanation

Methodology

How the CSV to XML Converter Works

AnyTool CSV to XML reads the uploaded file with the browser FileReader API and parses it with a full RFC 4180 reader, so commas, quotes and newlines inside quoted fields are handled correctly. The delimiter (comma, semicolon, tab or pipe) is auto-detected from the first line, and the header row supplies the column names. To build the document it wraps every data row in a configurable row element inside a single configurable root element, and for each column it either emits a child element or, if you toggle that column, an attribute on the row. Header names are sanitised into valid XML names — illegal characters become underscores and names starting with a digit get an underscore prefix — and every value is XML-escaped. The XML is regenerated live in a debounced effect as you change options, with nothing sent to a server.

  • RFC 4180 parser with automatic delimiter detection
  • Configurable root element (default <data>) and row element (default <record>)
  • Per-column choice of child element or attribute on the row
  • Header names sanitised to valid XML names; values XML-escaped
  • Conversion regenerates live in the browser — no server round-trip
How It Works

Element vs Attribute Mapping and CDATA

XML can represent a CSV column two ways, and AnyTool lets you decide per column. Element mode writes each value as its own child tag (<email>alice@example.com</email>), which suits repeated or structured data; attribute mode writes it as name="value" on the row element (<record id="1">), which suits identifiers and metadata. Duplicate attribute names are de-duplicated automatically. For text that contains markup-like characters you can wrap element content in CDATA — either always or only when a value contains <, > or & — and any embedded ]]> sequence is split safely so the document stays well-formed. Empty cells follow a policy you choose: skip the element, emit an empty <tag/>, or mark it with xsi:nil="true".

  • Click any column to switch it between element and attribute output
  • Mixed element/attribute documents in one conversion
  • Optional CDATA wrapping with safe ]]> splitting
  • Empty-cell policy: skip, empty element, or xsi:nil
  • Optional XML declaration, namespace URI and 2- or 4-space indent
Privacy & Security

Privacy and Offline Use

The entire conversion — parsing the CSV and generating the XML — runs in client-side JavaScript, so the file never leaves the device, there is no account or tracking, and the tool works offline after first load. That matters because CSV exports frequently contain personal or commercial records. Output can be downloaded as a .xml file in UTF-8, UTF-16 or ISO-8859-1, or copied to the clipboard, all within a 50 MB input cap and uploading nothing.
