You gave two different things you want to accomplish: 1. “I am trying to read those values and store in DB” 2. “I will populate the struct and provide it the application for consumption”
Fortunately accomplishing either or both of these goals follows a similar process. Start by figuring out what the output should be. In the case of a DB, the schema the data will be put into. For providing it to the application, the data structures you want. You mentioned using range, which means the data you want to range over needs to be in a slice or a map. Then extract and transform the input into the output. Some guesses I have made about your data: - There are a variable number of applications and their names aren’t known before you get the data. - Applications have different parameters - Parameter types default to the contents of “parameterType”, in this case “common” Assuming these guesses are correct, I would unmarshal the json into: struct { JsonData []struct { DataReference []struct { ParameterType string `json:"parameterType"` ApplicationType map[string]map[string]interface{} } `json:"dataReference"` } `json:"jsondata"` } This sets out the known portions and leaves the variable portions for later handling. Then iterate over ApplicationType to get the different applications and their parameters. Populate the database or desired data structures during the loop.
