Filtering and getting Items from a Sharepoint ListView

Filtering reduces the number of items displayed in a view to just the data your want to see. A filter selects items that match specific criteria, such as location, type of item, or a range of prices. Using indexes and filters can also help you get you back into your data or prevent exceeding the List View Threshold. A filter can return data by itself or be grouped or sorted for better formatting.

Thanks for replying Ronika. My requirement is to query a specific custom standard View(eg-MonthlyView) from a SP Online list and based on the CAMLQuery results would want to copy the results into another SP Online list and also set a PeoplePicker field in the 2nd list with the CreatedBy User from the items returned by the CAML Query
