Get Label For SObject API Name

Question

I have an exhaustive list of custom objects whose API Names and labels does not match. I end up opening each object in order to determine if the label has matching API Name.I want to see the API Name displayed along with label on the result page of custom Objects. Is there a better way to get label for a custom object when its API Name is known?

Answer 1

You can get the label using the DescribeSObjectResult:

DescribeSObjectResult describe = SObjectType.MyApiName__c;
system.debug(describe.getLabel());

Another common syntax is:

DescribeSObjectResult describe = MyApiName__c.sObjectType.getDescribe();

You can also just one-line it:

system.debug(SObjectType.MyApiName__c.getLabel());

Answer 2

The OP asked how to handle an

exhaustive list of custom objects

not just 1 at a time.

For built-in sObjects, the Label is usually the same as the API name but with spaces. Unfortunately there are exceptions for example

API Name: OpportunityLineItem UI Label: Opportunity Product

Custom sObjects can be anything, so you'll need to get a map of all of their API names and Labels. Much of that comes out of the box with Schema.getGlobalDescribe(); The code below worked for me to put the API Name next to the Label.

    Map<String, SObjectType> sObjects = Schema.getGlobalDescribe();
    for (String apiName : sObjects.keySet()) {
        // As far as I know all custom sObject API names end in __c   
        if (!sObjects.get(apiName).getDescribe().getName().endsWith('__c')) {
            // Replace spaces with empty string
            System.debug(sObjects.get(apiName).getDescribe().getName() + ' - ' + sObjects.get(apiName.replaceAll('\\s+', '')).getDescribe().getLabel());
        } else {
            System.debug(sObjects.get(apiName).getDescribe().getName() + ' - ' + sObjects.get(apiName).getDescribe().getLabel());
        }
    }

Now that the SFDX CLI is available however, I would install it and write a fake test that runs the code above and then redirect it to the CLI.

From there, you could further redirect that output to a file, which would be pretty easy to convert to a basic HTML or VisualForce table.

You probably have the same issue with custom fields. There are now browser plugins for Firefox and Chrome which do an OK job of displaying the fields in Classic Mode
