26 Jul 202324 minutes to read
Importing allows you to view or edit the predefined conditions which is available in JSON or SQL. You can import the conditions either initial rendering or post rendering.
Initial rendering
To apply conditions initially, you can define the rule. Here, you can import structured JSON object by defining the rule property.

Exporting allows you to save or maintain the created conditions through the Query Builder. You can export the defined conditions by the following ways.
Exporting to JSON
You can export the defined conditions to structured JSON object through the getRules method.
Exporting to SQL
You can export the defined conditions to SQL query through the getSqlFromRules method.
