Handling missing JSON values

While merging employee data, you notice some records have incomplete information marked as "N/A". Before analysis, you need to identify these gaps and handle them properly.

Tablesaw can be configured to recognize custom placeholders as missing values, allowing you to detect and filter incomplete records.

The JsonReader, JsonReadOptions, and Table classes have been imported for you.
