json_extract Function

Syntax

C text = json_extract(json_text as C, property_name as C)

Arguments

json_textCharacter: A string that contains the JSON object to search.
property_nameCharacter: The name of the property to find and extract from the JSON object.

Description

Extracts a property from a JSON object.

Discussion

The JSON text passed to the function must be properly formed (i.e. use double quotes on property and string names). You can use json_reformat_safe() to 'clean' up the JSON string before calling json_extract.

Example

dim json as c 
json = <<%txt%
{ 
    name: 'Fred',
    address: {
        street: '123 Main St',
        city: 'Boston',
        state: 'MA'
    }
}
%txt%

'json_extract() requires properly formed JSON, so
'we first call json_reformat_safe()
dim json2 as c 
json2 = json_reformat_safe(json)

?json_extract(json2,"name")
= "Fred"

?json_extract(json2,"address")
= {
        "street": "123 Main St",
        "city": "Boston",
        "state": "MA"
    }
