Why XML won't open
Most "won't open" issues are format mismatches (the extension says XML but the bytes say otherwise) or unsupported variants (a specific sub-flavor of XML the receiver's software doesn't handle).
Converting to JSON with XML to JSON Converter re-encodes the content into a clean, standards-compliant file. Whatever weirdness the original had, the output of XML to JSON Converter is a fresh, well-formed JSON.
