Q: “How do I run ‘Where Is this Used?’ on all custom fields at once?”
A: Jupyter notebook spfy-where-used!
spfy-where-used leverages the “Simple Salesforce” Python library and Tooling API calls to generate a spreadsheet of all custom fields’ “Where Is this Used?” results.
Update the config.py file in the resources subdirectory to reflect your org’s username, password, and security token.
Sadly, “Where Is this Used?” doesn’t cover Workflow or Data Validation. 😐
