xml-to-json-fast

Fast, light converter of xml to json capable of handling huge xml files

The fast, simple xml-to-json-fast executable provides an unambiguous one-to-one mapping of xml data to json data. It is suitable for very large xml files (has been tested on a 500MB file) and uses very little memory. However, xml-to-json-fast doesn't provide for any control over the output. Please see the other project, xml-to-json.

When using "fast" (xml-to-json-fast), the output reflects the exact structure of the xml, which is allowed to be somewhat malformed (resulting in invalid json).

Formatting: Currently xml-to-json-fast does not format the resulting json. If whitespace formatting is required, you can use a json formatting program such as aeson-pretty (on debian/ubuntu, can be install with sudo apt-get install aeson-pretty). Note that most of the json formatters are memory bound, so very large json files may cause the formatter to run out of memory.
