JSON (JavaScript Object Notation) is a lightweight data-interchange format.

Json Box is a C++ library used to read and write JSON with ease and speed.

Things it does:

• Follows the standards established on http://json.org/
• Read and write JSON in UTF-8
• Uses the STL streams for input and output
• Generated JSON can be indented and pretty or compact and hard-to-read
• Does not crash when the JSON input contains errors, it simply tries to interpret as much as it can

Things it does not do:

• Read JSON in UTF-16 or UTF-32
• Keep the order of the members in objects (the standard doesn't require keeping the order)
• Write useful error messages when the JSON input contains errors

The library wasn't designed with multi-threading in mind.
