Microsoft released the most awaited feature of SharePoint list column
formatting. Using this feature users can easily find list item value by
different colour, indicator icon, bar chart,etc.. and also support
custom action from column field, so user can modify list view with their
own style

How column formatting is working ? Column formatting is working with
Json functionality and json file contains condition and predefined
class. You can create your own json file with required condition or you
can use already existing PnP sample json files based on your requirement

Common Nodes in JSON

• elmType – Specifies the element type like DIV, span , A
• debugMode – An optional property that is meant for debugging
• attributes – An optional property that specifies additional
  
  attributes to add to the element
• class – Specifies the predefined class for style and action
• operator – Specify the type of operation to perform like =, -, +,
  
  <, >, <=, etc…
• operands – Specifies the parameters, or operands for an expression
