    Importing From JSON

    Icon

    Importing from JSON is available since BellaDati 2.9

    BellaDati also allows users to import data from JSON file. By using special transformation functions, it is possible to parse JSON arrays and objects.

    In some cases, it might be necessary to change Array element to correctly parse the data into rows. This can be done in the import settings.

    After choosing the Array element correctly, it is possible to use the function parseJSON() to load the JSON value into a variable and then access the values by using functions getString(), getInteger(), getDouble(), etc. to load the values. To access a nested object, users have to use function getJSONObject(). To access an array, function getJSONArray() is available.

    Examples

    Let's have a JSON file with following structure:

    To be able to get the values, users need to specify sales as Array element. 

    To get the category, add a new column as an attribute and use following code:

    To get the total items, add a new column  as an indicator and use following code:

    To calculate the total price from all the item prices, use this formula:


    Let's have this JSON:


    To access value from the JSONArray, use this formula:
