Retrieve metadata (Custom labels, Validation Rule, Workflow Rule, Profile, Permission Set, Email Template, Field Set, Static Resource, User, Apex Class, Apex trigger, custom object, custom metadata type, custom setting) in a Salesforce org in just one single click. We DO NOT need to browse through the multiple pages (problem gets worse when there are hundreds or thousands of custom labels defined in your org) or query in developer console or run a script in anonymous window. Therefore it saves a lot of clicks and time. In addition to above now you can execute SOQL, SOSL, fetch SOQL Query Plan. User can also Analyze Debug Logs and get different meaningful insights from the debug logs. User can also get complete record level details with just one click and get more info of the currently logged-in user in the Salesforce org. User can also get a feature of JSON formatter which can format any JSON. User also gets a feature of JSON2YAML converter.
