How to convert CSV to JSON in Java

If converting CSV format into JSON seems like a daunting task, then take heart! In this tutorial we will be tackling this problem easily and efficiently, with almost no coding required on your end. All in all, this will save you hours of setting up and testing parsing and reformatting options.

To start off our process, we need to add Jitpack to our list of repository references.


Next, a dependency for our API client.


Lastly, our function call:

// Import classes://import com.cloudmersive.client.invoker.ApiClient;//import com.cloudmersive.client.invoker.ApiException;//import com.cloudmersive.client.invoker.Configuration;//import com.cloudmersive.client.invoker.auth.*;//import com.cloudmersive.client.ConvertDataApi;ApiClient defaultClient = Configuration.getDefaultApiClient();// Configure API key authorization: ApikeyApiKeyAuth Apikey = (ApiKeyAuth) defaultClient.getAuthentication("Apikey");Apikey.setApiKey("YOUR API KEY");// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)//Apikey.setApiKeyPrefix("Token");ConvertDataApi apiInstance = new ConvertDataApi();File inputFile = new File("/path/to/file"); // File | Input file to perform the operation on.Boolean columnNamesFromFirstRow = true; // Boolean | Optional; If true, the first row will be used as the labels for the columns; if false, columns will be named Column0, Column1, etc.  Default is true.  Set to false if you are not using column headings, or have an irregular column structure.try {Object result = apiInstance.convertDataCsvToJson(inputFile, columnNamesFromFirstRow);System.out.println(result);} catch (ApiException e) {System.err.println("Exception when calling ConvertDataApi#convertDataCsvToJson");e.printStackTrace();}

And would you believe that we are already done? Easy!
