Get the record Count of all countable Sobjects in Salesforce

 Salesforce: Get the record count of all objects

Use case: A client wants to access the data volume for data migration and needs to get record counts from all countable objects in Salesforce

Solution: 
1) log in to Workbench
2) Go to Utilities > Rest Explorer
3) Do a GET call on this URI: /services/data/v56.0/limits/recordCount ( change 56.0 with the latest API version)
4) Check the result. Copy the JSON and convert it to CSV

Note:
1) The Rest call result does not include uncountable objects and record count for deleted records in the recycle bin
2) Ensure your user has "View Setup and Configuration” permission
