Flatten To JSON (G Dataflow)

Last Modified: December 18, 2017

Converts data to a UTF-8 JavaScript Object Notation (JSON) string.

enable LabVIEW extensions

A Boolean that determines whether JSON extensions support NaN and Inf values of floating-point numbers. Not all JSON parsers support these extensions.

True Enable JSON extension support of NaN and Inf values of floating-point numbers.
False Disable JSON extension support of NaN and Inf values of floating-point numbers.

Default: True

datatype_icon

anything

The data you want to convert to a UTF-8 JSON string. This input accepts arrays and clusters of Booleans, floating-point numbers, and strings. anything can also accept an array of clusters, or a cluster of arrays, of these data types. This input does not support other data types, such as enums, refnums, file paths, and fixed-point numbers. Cluster elements may be named or unnamed, but not a combination of both. If cluster elements are named, then each name must be unique to that cluster.

datatype_icon

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

JSON string

The flattened data encoded in UTF-8. UTF-8 encoded strings may not display correctly.

error out

Error information.

The node produces this output according to standard error behavior.
