JSON

{
    "value1": 7, 
    "value2": 11, 
    "value3": 13
} 

will create the following variables:

VarName_value1	VarName_value2	VarName_value3
7	11	13

Nested objects and arrays

Nested objects and arrays are flattened into one variable per value: the names are joined with _, and array items are numbered from 0. Spaces anywhere in the resulting name, the variable name included, become _.

{
    "motor": {
        "speed rpm": 1450,
        "phases": [230, 231]
    }
}

will create the following variables:

VarName_motor_speed_rpm	VarName_motor_phases_0	VarName_motor_phases_1
1450	230	231

Reserved keys

The keys s, t, q and c are reserved. Capture Edge skips any key with exactly one of these names, at any level and together with everything nested under it, without logging anything. The check is case-sensitive, so T is kept.

{
    "t": 21.5,
    "h": 40
}

only creates VarName_h: the value of t is lost. Rename such keys, for example to temperature.
