What Is XML?
XML (Extensible Markup Language) is a flexible, text-based format for structuring, storing, and transporting data. Defined by the W3C, XML uses self-describing tags to organize data hierarchically, making it both human-readable and machine-parseable.
Unlike HTML (which displays data), XML carries data without any predefined tags — you define your own
element names to match your domain. XML remains widely used in enterprise systems, SOAP web services,
configuration files (e.g., .csproj, web.config, Maven pom.xml),
office document formats (OOXML, ODF), and data interchange standards (HL7, XBRL, SVG).
What This Tool Does
- Validate — Check that your XML is well-formed and report any syntax errors with line numbers.
- Beautify — Format compressed XML with proper indentation for readability.
- Minify — Strip whitespace to reduce file size for production or network transfer.
- Convert to JSON — Transform XML into equivalent JSON for REST APIs or JavaScript consumption.
- Convert to YAML — Output human-friendly YAML notation from XML data.
- Convert to CSV — Flatten XML tables into comma-separated values for spreadsheets.
- Convert to Base64 — Encode XML as a Base64 string for embedding or safe transport.
- Convert to String — Escape XML for embedding inside other XML or code strings.
How to Use
- Paste your XML into the input area, or drag and drop a .xml file onto the drop zone.
- Click the operation you need — Validate, Beautify, Minify, or choose a target format from the Convert dropdown.
- View the result in the output area below. Copy it to your clipboard or save it.

Common XML Use Cases
- Configuration Files: .NET projects (
.csproj,web.config), Android manifests, Maven builds. - Data Exchange: SOAP web services, RSS/Atom feeds, financial reporting (XBRL).
- Document Formats: Microsoft Office (OOXML), LibreOffice (ODF), SVG graphics.
- Healthcare: HL7 CDA/FHIR messages between hospital systems.
- Government & Legal: UBL invoices, court filings, regulatory submissions.
Frequently Asked Questions
Well-formed XML follows basic syntax rules: a single root element, properly nested and
closed tags, case-sensitive tag names, and quoted attribute values. An XML document that
violates any of these rules will cause a parsing error in every compliant XML processor.
Absolutely. While JSON dominates web APIs, XML remains the standard in enterprise
integration (SOAP, EDI), document formats (Office, SVG), regulated industries
(healthcare HL7, finance XBRL), and configuration files (.NET, Android, Maven).
XML's schema validation and namespace support make it essential for complex, multi-party
data exchange.
