Frequently Asked Questions
What does this tool do?
This tool decodes Base64-encoded strings and validates them as XML, displaying the decoded XML content. It's perfect for inspecting encoded XML data from APIs, configuration systems, or data exchange platforms.
What if the decoded data isn't XML?
The tool will show an error if the decoded Base64 string doesn't contain valid XML format. In that case, you may want to use the Base64 to ASCII tool instead to see the raw decoded text.
Does this tool format XML?
The tool displays the XML exactly as it was encoded. If the original XML was formatted with indentation, it will appear formatted. If it was minified, it will appear on one line. The tool validates the XML but doesn't reformat it.
Is my data safe?
Absolutely! All decoding happens entirely in your browser using client-side JavaScript. No data is ever sent to any server, ensuring complete privacy and security for your XML content.
Can I use this for SOAP messages?
