What is XML Validator and how does it work?

XML Validator is a free online tool that lets you quickly and easily check whether your XML is valid. Besides working as an XML checker, it also functions as an XML formatter. You can minify or beautify your XML content with ease. To use the tool, simply paste your XML content into the editor (or select an XML file from your device) and validate it with a single click.

Can I minify and beautify XML data with this tool?

Yes. XML Validator lets you both minify (make XML more compact) and beautify (format XML to make it more readable). In software development, both formatting styles are useful depending on the situation. Sometimes you may need to beautify XML to make it easier to read and debug. Other times you might want to minify XML to reduce file size by removing unnecessary whitespace, line breaks, and XML comments.

How can XML Validator help me?

XML Validator helps you quickly identify and fix errors in your XML data and format it according to your requirements. Properly validated and formatted XML ensures your data is reliable, well-formed, and ready for use in applications and APIs.

Can XML Validator process XML-based localization files?

XML Validator is mainly built to validate and format XML. It can also handle several common XML-based localization formats (even if they use different file extensions), including Android Resources, Angular XLIFF, .NET Resources, Apple Stringsdict, and TMX.

If you need localization-specific features beyond XML validation and formatting, a specialized localization tool may be a better fit.

Can I enter confidential information into XML Validator?

XML Validator processes your data entirely within your browser and does not send it to external servers, which generally makes it safe to use. However, it’s good practice to avoid entering sensitive information, such as passwords or API keys, into any tool.
