XML to CSV & CSV to XML Converter

XML and CSV Converter: Core Features and Principles

When you need to export hierarchically structured XML data into a CSV format suitable for spreadsheet software, or convert flat CSV tables into machine-readable XML, this tool provides a standardized solution. XML (eXtensible Markup Language) defines data structure through tags, while CSV (Comma-Separated Values) stores tabular data in rows and columns. This tool parses the XML node tree to generate CSV headers and field values, or automatically builds XML hierarchical tags based on CSV headers, achieving lossless conversion between the two formats.

Why Choose Our XML to CSV Converter?

• Bidirectional Lossless Conversion: Fully preserves XML attributes, node hierarchies, and CSV row/column structures. Supports processing of comments and declaration headers.
• Deep Configuration Capabilities: Customize delimiters (commas, tabs, etc.), XML indentation, compact mode, and null value handling rules.
• Real-Time Preview: Configuration adjustments take effect immediately, allowing you to verify conversion results without resubmitting.

How to Use

1. Paste valid XML or CSV source data into the left editor.
2. Set conversion parameters on the right: configure delimiters and headers for XML to CSV, or set indentation and attribute handling for CSV to XML.
3. Copy the converted data directly from the result area. UTF-8 encoding is supported to prevent garbled text.

Frequently Asked Questions (FAQ)

• Is there a file size limit for conversion?
  We recommend processing data under 1MB. For extremely large datasets, process them in batches to ensure fast response times.
• How are headers mapped when converting CSV to XML?
  The tool automatically uses the first row of the CSV as XML child node tags. For example, a header named "ID" will generate an <ID>value</ID> node.

Important Notes

• XML input must comply with W3C specifications; avoid unclosed tags.
• The CSV delimiter must match the actual data.
• We recommend processing sensitive data locally. This online tool does not persist user data.
• Complex nested XML conversions may require manual adjustment of hierarchical mapping relationships.

Technical Notes

For XML files containing CDATA sections, the original text content will be preserved during conversion to avoid escaping errors. A typical example:
Input CSV: "ID,Name 1,John" → Output XML: <root><row><ID>1</ID><Name>John</Name></row></root>
