Some of data fields missing

Hi, Evgeny!
 
Thank you for writing to us.
To start working with the data successfully, we recommend referring to the following articles from our documentation, which provide with all the details on preparing and loading your data into the pivot table component:

• JSON Data Source
• CSV Data Source
• JSON Data Types. This article may help you to understand how to set types for the fields of the JSON data.
• CSV Data Types. This article explains how to define types in the CSV data. 

The type of behavior you’ve described may occur if you omit the definition of certain fields in the first object of your JSON data. As you may learn from the above-mentioned articles, the first object is responsible for defining the data types for your fields. 
 
Hope this will be helpful for your case. Please contact us in case any questions or problems.
 
Regards,
WebDataRocks Team
 

Thank you. 
Just missed The first object that defines data.
