XML works by providing a predictable data format. XML is strict on formatting; if the formatting is off, programs that process or display the encoded data will return an error. For an XML document to be consideredwell-formed-- that is, conforming to XML syntax and able to be read and un...
You don’t run a JSON file. It’s not executable like an EXE file. It’s a readable text file. This means you can open it using most text editing programs. However, not all of them allow you to also edit the file, and doing this with some might ruin the formatting of the text....
