Take a snapshot of a policy to identify the holders and the amount of tokens they are holding
The primary application of a policy snapshot is to identify the holders of a specific policy and then use that information to airdrop tokens to the holders or to create a whitelist. You can use the policy snapshot tool with any Cardano policy ID.
Go to the 'Policy Snapshot tab' via the menu bar.
Enter any policy ID you want t snapshot and click 'Search'.

The application will now scan the policy and list all tokens, their addresses, quantities, and supplies.
Overview of the policy snapshot
If you want to use the policy snapshot for whitelisting, it makes sense to cumulate the amount of tokens that a wallet holds for each stake address. If you enable this option, you will receive a list that summarizes the tokens of each stake address and each wallet will be listed only once.
Cumulate the amount of tokens for each stake address
The column "TotalQuantity" will now show the cumulated amount of tokens this stake address is holding. The column "Quantity" shows the amount of tokens of the Receiver address.
