Which tool should you use to programmatically modify every column whose name ends with "Key" in a semantic model?

• A. Microsoft Power BI Desktop
• B. ALM Toolkit
• C. Tabular Editor
• D. DAX Studio

Answer: (C)

The key idea is performing bulk, pattern-based edits to a semantic model, which requires a tool with a programmable API for model metadata. Tabular Editor is built for exactly that: it connects to your tabular model and lets you write scripts that traverse all tables and columns, filter by a condition (like a name ending with "Key"), and apply changes across many objects in one run. This makes it ideal for modifying every column whose name ends with "Key" without tedious manual edits.

Power BI Desktop is great for interactive development but doesn’t offer a robust scripting interface to batch-edit many model objects. ALM Toolkit focuses on schema comparison and deployment rather than direct in-model edits. DAX Studio is for running DAX calculations and queries, not for editing the metadata of the semantic model.
