Can you please add more details about your requirement & conditions to check?
Do you want to show the column value as "Active" when current (today's) date is in between Start date and End Date? Or if both the Start date and End date are in current month?

What is the internal name of Start date and End date columns?
In JSON formatting, you need to use internal name of your columns to refer their value in JSON code. Check below documentation to find out the internal names of start date and end date. and use those in place of [$StartDate] and [$EndDate].

Thanks for your help, anyway do you know how to give color (example, active will be green, non active will be red).
Use below code for changing colors:
{ "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json", "elmType": "div", "txtContent": "=if(@now >= [$StartDate] && @now <= [$EndDate], 'Active', 'Non Active')", "style": { "color": "=if(@now >= [$StartDate] && @now <= [$EndDate], 'green', 'red')", "font-weight": "bold" } }For more information related to styling refer: Use column formatting to customize SharePoint
