How to Mass Delete Custom Fields in Salesforce? (Step-by-Step Guide)

In this guide, we’ll cover two ways to delete custom fields in Salesforce:

• Delete custom fields manually using Salesforce Setup
• Mass delete custom fields using BOFC

Why Organizations Delete Custom Fields in Salesforce?

Custom fields are often created to support new business requirements, integrations, or temporary projects. Over time, however, many of these fields become obsolete.

Common reasons for deleting custom fields include:

• Removing unused or redundant fields
• Cleaning up page layouts
• Simplifying reports and dashboards
• Preparing for Salesforce migrations
• Improving org maintainability
• Reducing metadata clutter

Regular field cleanup helps administrators keep Salesforce organized and easier to manage.

Steps:

• Go to Object Manager
• Select the object
• Open Fields & Relationships
• Delete fields one by one

Limitations of the Manual Approach

While the native Salesforce method is straightforward, it becomes inefficient when dealing with large numbers of fields.

Administrators often encounter challenges such as:

• Repeating the same process for every field
• Spending significant time on cleanup projects
• Managing deletions across multiple objects
• Increased chances of overlooking fields

For large-scale metadata cleanup initiatives, a bulk management approach can be more efficient.

Method 2: Mass Delete Custom Fields Using BOFC

User can display list of fields using two methods:

1. Show Directly: Once objects are selected and this method is selected, on clicking “Display Custom Fields”, it will display the list of custom fields for the selected objects in the form of table.
2. Using XLS: User can download the XLS file for all the custom fields for the selected objects. User can filter the sheet and can mark which fields needs to be deleted. Once the sheet is ready, user can upload the final sheet and can delete multiple fields in single click.
