Implementations are free to set limits on JSON documents, including the size, so choose your parser wisely. See RFC 7159, Section 9. Parsers:

"An implementation may set limits on the size of texts that it accepts. An implementation may set limits on the maximum depth of nesting. An implementation may set limits on the range and precision of numbers. An implementation may set limits on the length and character contents of strings."

It depends on the implementation of your JSON writer parser   Microsoft s DataContractJsonSerializer seems to have a hard limit around 8kb  8192 I think   and it will error out for larger strings   Edit  We were able to resolve the 8K limit for JSON strings by setting the MaxJsonLength property in the web config as described in this answer  https   stackoverflow com a 1151993 61569

There is no fixed limit on how large a JSON data block is or any of the fields    There are limits to how much JSON the JavaScript implementation of various browsers can handle  e g  around 40MB in my experience   See this question for example

Surely everyone s missed a trick here  The current file size limit of a json file is 18 446 744 073 709 551 616 characters or if you prefer bytes  or even 2 64 bytes if you re looking at 64 bit infrastructures at least   For all intents  and purposes we can assume it s unlimited as you ll probably have a hard time hitting this issue

JSON is similar to other data formats like XML - if you need to transmit more data  you just send more data  There s no inherent size limitation to the JSON request  Any limitation would be set by the server parsing the request   For instance  ASP NET has the  MaxJsonLength  property of the serializer
