JSON

A Streamsheet has the possibility to process, generate and accumulate data. Before sending this data, the cells from a data range have to be structured, in order for an App to interpret them correctly. JSON() is paring two columns together to a key and value pair using the JSON Syntax. Alternatively it is possible to specify a text which will be parsed to JSON or use one of the various INBOX/OUTBOX functions to reference an element from a message stored in inbox or outbox respectively. The optional second parameter can be used to convert the resulting JSON object to a textual representation. This function is mostly used within publish functions like: MQTTPUBLISH. The JSON structure supports quotes "". eg. {"Key":"value"}

=JSON(DataRangeOrTextOrInboxOutboxFunction,ResultAsText)

Arguments
