Is there a way to mass delete inactive workflow rules

Salesforce doesn’t offer a native way to mass delete inactive workflow rules, so cleaning them up manually can take a while.

A couple of options:

• Metadata/API tools like Workbench or VS Code + Salesforce CLI if you’re comfortable with deployment. 
• BOFC (Bulk Object Field Creator) if you want an admin-friendly way inside Salesforce—it can bulk delete workflow rules across multiple objects without going one by one. 

For org cleanup with lots of inactive rules, a bulk tool definitely saves a lot of time.
